I'm using boost program options for my project but I can't get program exit without crashing. It crashes after exiting main function.

I'm using cmake with such options:
set(Boost_USE_STATIC_LIBS OFF)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
set(Boost_ALL_DYN_LINK ON)
I tried static linking and it worked for some time but now it crashes with any settings.
OS: Debian Squeeze
If it helps https://github.com/Intel/poolserver this is my source
Your question doesn't give us the code directly, but looking through github, I suspect the boost program options have nothing to do with it.
The error says
double free or corruption
I suspect it's this:
void DatabaseConnectionMySQL::Close()
{
delete this;
}
Problem was with boost package from debian. Compiling newest boost from source fixed crash.

I'm trying to execute a very basic C++ program that interacts with MySQL. I implemented the very beginning of the tutorial for MySQL Connector/C++, but I keep getting a segfault when I try to execute that code. Here is the code that I'm trying to execute:
try
{
sql::mysql::MySQL_Driver *driver = NULL;
sql::Connection *conn = NULL;
driver = sql::mysql::get_mysql_driver_instance();
if (driver != NULL)
{
conn = driver->connect("127.0.0.1:3306", "root", "root");
cout << "Test" << endl;
}
delete conn;
conn = NULL;
}
When I execute this code, "Test" gets printed, but I get the following error:
*** Error in `./test': free(): invalid pointer: 0x00007f0a9a292158 ***

This is so basic - what am I doing wrong?
Thank you very much for any help.
I am having this segmentation fault after a colleague of mine committed some new features on our project. The new feature has no impact on the following function, but only increases the QString argument size.
After some debugging, I've figured out that segmentation fault was happening after the following function return.
I need to know why does it is happening and why my workaround worked, and if the workaround is safe?
I must say that the following snippet it is working on older version of Qt (5.3.1 with gcc 4.8) that I have now installed (Qt 5.9 with gcc 7.0).
It also works nicely on Debug rather that Release compiling mode on Qt.
Finally, I don't want to discuss the effectiveness of this encryption method, but the entitled problem.
The crashes happens immediately after function returning, I have no idea why.
QString Utility::encrypt(QString text)
{
QByteArray textUtf8 = text.toUtf8();
// Convert QString to Char
const char *srcString = textUtf8.constData();
char encrypted[ textUtf8.size() ];
// Copy Char by Char
strcpy(encrypted,srcString);
for(int u=0; u<textUtf8.size(); u++ ){
encrypted[u]++;
}
return QString::fromUtf8(encrypted);
}
The output from Segmentation fault is:

The workaround I've figured out was the following:
char encrypted[ textUtf8.size() + 1 ];
However, I confess that I don't know why it worked. Could someone explain it?
Is there any better solution?
The problem is that data in the QByteArray returned by text.toUtf8() is not NUL-terminated, and strcpy() expects a NUL-terminated string... since it doesn't get one, it will happily keep copying extra garbage-bytes past the end of your encrypted array until it finally does encounter a zero-byte somewhere, and corrupt your stack, which leads to the crash when the function returns.
Also, your encrypted array is not large enough to hold the NUL byte that strcpy() wants to place in it.
A fix would be something like this:
char encrypted[ textUtf8.size() + 1 ]; // +1 to hold the NUL terminator byte
memcpy(encrypted, srcString, textUtf8.size() );
encrypted[textUtf8.size()] = '\0'; // place NUL-terminator byte
[...]
Also, a portability note: dynamically-sized arrays aren't part of the C++ standard, so your declaring char encrypted[ textUtf8.size() + 1]; is working for you only because your compiler includes a non-standard extension to enable that. If you want your code to be portable (as all self-respecting Qt code should be ;)), you may want to use a std::vector or other similar higher-level mechanism instead of a dynamically-sized array.
char encrypted[ textUtf8.size() + 1 ];
Because of size we have to use a null character to terminate a string array
For example try this
#include<iostream>
#include<string>
using namespace std;
int main()
{
char textUtf8[5] ="hello";
}
You will see warning "Initializer string for char array is too long"
I am doing some image processing stuff however when I try to show an image which is originated from my webcam I get the following output to my terminal:
debug end of loop

This is what my code looks like:
int main(int argc, char** argv)
{
while(1)
{
while(1)
{
// some algorithms
cerr<<"debug end of loop"<<endl;
}
imshow("imgFrame", imgFrame);
cerr<<"debug 1"<<endl;
char c = (char)waitKey(10);
cerr<<"debug 2"<<endl;
if( c == 27 ) break;
cap >> imgFrame;
}
return 0;
}
the corresponding valgrind output: https://pastebin.com/ch1h2aFL
Could someone explain me what I may be doing wrong? is this an openCV bug?
the code being used: https://pastebin.com/brtR3eHn
You call imshow first, cap>>imgFrame later which might be the cause at the first run.
I wrote simple code to try to post data in CURL in a while loop. I'm getting an error that CURL failed to initialize. I ran the simple tutorial that given online, that works and CURL initialized, but I'm having trouble with my code. Please help
I'm new to C++ and very new to CURL so please do explain in more details how to proceed.
Code:
#include <iostream>
#include <string>
#include <sstream>
#include <stdio.h>
#include <curl/curl.h>
using namespace std;
int main(void)
{
// Variables
const char *Myurl = "http://127.0.0.1:3000";
const char *Myid = "My_ID_0";
CURL *curl;
CURLcode res;
/* In windows, this will init the winsock stuff */
curl_global_init(CURL_GLOBAL_ALL);
/* get a curl handle */
curl = curl_easy_init();
if(curl) {
/* First set the URL that is about to receive our POST. This URL can
just as well be a https:// URL if that is what should receive the
data. */
curl_easy_setopt(curl, CURLOPT_URL, Myurl);
/* Now specify the POST data */
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, Myid);
}
double value1[6] = {-6,-5,-4,-3,-2,-1};
double value2[6] = { 1, 2, 3, 4, 5, 6};
for(int i=0; i<6; i++){
string stringvalue1 = std::to_string(value1[i]);
string stringvalue2 = std::to_string(value2[i]);
const char *Myvalue1 = stringvalue1.c_str();
const char *Myvalue2 = stringvalue2.c_str();
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, Myvalue1);
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, Myvalue2);
/* Perform the request, res will get the return code */
res = curl_easy_perform(curl);
/* Check for errors */
if(res != CURLE_OK)
fprintf(stderr, "curl_easy_perform() failed: %s\n",
curl_easy_strerror(res));
/* always cleanup */
curl_easy_cleanup(curl);
cout << "URL output should be: " << Myurl << "/" << Myid;
cout << "/" << Myvalue1 << "/" << Myvalue2 << endl;
}
curl_global_cleanup();
return 0;
}
Error:
curl_easy_perform() failed: Failed initialization

I am running on ubuntu machine with netbeans to compile. Compilation goes like this:
g++ -c -g -I/u01/app/oracle/product/12/dbhome_1/rdbms/public -MMD -MP -MF "build/Debug/GNU-Linux/main.o.d" -o build/Debug/GNU-Linux/main.o main.cpp
mkdir -p dist/Debug/GNU-Linux
g++ -o dist/Debug/GNU-Linux/occi_test build/Debug/GNU-Linux/main.o -L/u01/app/oracle/product/12/dbhome_1/lib -lnnz12 -locci -lclntsh -lipc1
After debugging, I can see that it crashes here (user, password and ip ommited, but I use the same user and password to connect to sqlplus), but I don't know why crashes:
this->user = "usr";
this->passwd = "pass";
this->db = "myip:1521/orcl";
this->env = Environment::createEnvironment(Environment::DEFAULT);
try
{
this->con = env->createConnection(this->user, this->passwd, this->db);
cout << "12cjd" << endl;
}
catch (SQLException& ex)
{
cout << ex.getMessage();
exit(EXIT_FAILURE);
}
From your output it isn't clear your catch block is catching anything.
If you properly cleanup the connection and environment, these errors may go away.
env->terminateConnection(con);
Environment::terminateEnvironment(env);
