Hi Brad,

I can reproduce the problem when compiling and running in a cygwin shell.
But if I change the code as follows, it works fine:

#include <fstream>
#include <iostream>
#include "systemc.h"

sc_clock sysClock;

int main() { // int return type instead of void

cout << "Hello, world!" << endl;
return 0; // use return instead of exit
}

This still doesn't explain why your original code fails, but it might help.
