segmentation fault with hello world. error in my g++ build? - c++

Question

I try to run this simple hello world :
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!" << endl;
return 0;
}
I have no error with g++ -g -Wall hello.cpp but when I execute ./a.out I have a segmentation fault.
Here is the gdb :
(gdb) run
*Starting program: /media/theflyingman/Share/C++/gcc_test/a.out
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".*
*Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7d3bf5a in std::ostream::sentry::sentry(std::ostream&) () from /lib/x86_64-linux-gnu/libstdc++.so.6*
(gdb) up

I can compile and execute this one (with gcc) :
#include <stdio.h>
int main() {
printf("Hello, world!\n");
return 0;
}
I have build gcc from sources.
gcc --version
gcc (GCC) 13.0.1 20230124 (experimental)

g++ --version

LinuxMint/kernel 6.1.7
I think I can have an error with my g++ build or an error with the library path but i'm not sure.
Any help ?
Best Regards
