std::endl crashes Windows 8, compiled using MinGW

I have 3 computers, two of which use Windows 8. Using the latest version of MinGW's g++ (4.8.1-4) my hello world program freezes whenever I compile and run on the Windows 8 computers but not in Windows 7.

#include <iostream>
int main()
{
    std::cout << "Hello, World!" <<std::endl;
    return 0;
}

This compiles just fine in g++ but running a.exe will display "Hello, World!" then a window will pop up and say "a.exe has stopped working, Windows can check online for a solution to the program...." etc.

Has anybody seen this problem.

Also, I tried "std::cout << "Hello, World!\n" << std::flush;" and this has the same problem. It seems that every function that flushes the buffer causes a crash.

Following Eric's advice, I recompiled the program and ran it in gdb and got the following output:

Program received signal SIGILL, Illegal instruction.
