RUN FAILED (exit value -1.073.740.940 ) - c++

Question

I'm quite new to c++ and netbeans and have quite a problem here and I can't put my finger on what the error might be.
Building is always succesful but I get a RUN FAILED (exit value -1.073.740.940, total time: 2s) error, when running my program. My code:
Arraylist.hpp:
#include <iostream>
namespace hfu {
class Arraylist {
private:
double* members;
int size;
public:
Arraylist(int);
~Arraylist();
Arraylist(const Arraylist&);
double get(int) const;
void set(int, double);
Arraylist& operator=(const Arraylist&);
//float operator[](int);
friend std::ostream& operator<<(std::ostream&, const Arraylist&);
};
}
Arraylist.cpp:
#include "Arraylist.hpp"
#include <exception>
namespace hfu {
Arraylist::Arraylist(int i) : size(i), members(new double[size]) {
for (int i = 0; i < size; i++) {
set(i, 0);
}
}
Arraylist::~Arraylist() {
delete members;
}
Arraylist::Arraylist(const Arraylist& other) : size(other.size), members(new double[other.size]) {
for (int i = 0; i < 5; i++) {
set(i, other.get(i));
}
}
double Arraylist::get(int i) const {
if (i < 0 || i >= size) {
throw (std::exception());
} else {
return members[i];
}
}
void Arraylist::set(int i, double value) {
if (i < 0 || i >= size) {
throw (std::exception());
} else {
members[i] = value;
}
}
Arraylist& Arraylist::operator=(const Arraylist& other) {
size = other.size;
for (int i = 0; i < size; i++) {
set(i, other.get(i));
}
return *this;
}
// float Arraylist::operator [](int index) {
// return members[index];
// }
std::ostream& operator<<(std::ostream& os, const Arraylist& list) {
for (int i = 0; i < list.size; i++) {
os << "[" << list.get(i) << "]";
}
return os;
}
}
main.cpp:
#include "Arraylist.hpp"
int main() {
try {
auto a1 = hfu::Arraylist(10);
std::cout << a1 << std::endl;
auto a2 = hfu::Arraylist(10);
std::cout << a2 << std::endl;
auto a3 = hfu::Arraylist(10);
std::cout << a3 << std::endl;
}
catch (std::exception& e) {
std::cout << e.what() << std::endl;
}
}
I can create 2 objects of Arraylist.... but not more, it will print the first two and then fail.... but when I create shorter lists, say 3 with only size one... it will work... so I think it might be something with the memory... but I'm at a loss. Ideas?
Thanks a lot!
btw: I'm using netbeans 8.2 and mingw g++ 6.1.0

Answer 1

The initialization order of the member variables is defined by the order of their definitions in the class, not by their order in the initializer list. As a matter of fact, your compiler should be giving you "hfu::Arraylist::size will be initialized after" warnings.
So in your case, members gets initialized before size, thus new double[size] is called when size is still garbage. In my case it simply causes std::bad_array_new_length to be thrown. In your case, things go worse and your application crashes.
So the solution is to change
class Arraylist {
private:
double* members;
int size;
to
class Arraylist {
private:
int size;
double* members;
