C++ basic program segmentation fault

Question

here is my CPP program

#include <iostream>

int main(int argc, char *argv[]){
     return 0;
}

compiling and executing this, causes a seg fault:

[18:08 ~] > g++ test.cpp
[18:09 ~] > ./a.out
Segmentation fault

Does anybody have an idea about this issue please? Thanks a lot for your help.

Here are some details that might be useful:

Thank you.

Answer 1

So apparently your problem is that your g++ installation is broken. I see from the messages that you have RHEL6, but somehow have version 3.4.6 of libstdc++.

My RHEL6 system has version 4.4.6 of gcc, libstdc++, etc. I assume that this older version of libstdc++ is related to your problem.

What versions do you have installed of gcc, g++, and libstdc++? From the other messages, it looks like you have 4.4.7, but do you happen to have multiple versions or mixed versions?

rpm -q gcc g++ libstdc++

Also, what other directories do you have under /usr/lib/gcc/x86_64-redhat-linux?

ls /usr/lib/gcc/x86_64-redhat-linux
