Q:

C++ basic program segmentation fault

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.

A:

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
