GoogleCodeExporter commented 8 years ago 
#include <stdlib.h>

double main()
{
    return 42;
}

Causes a segmentation fault.

I didn't bother to see why this happens, but a simple fix is to enforce a VOID 
or INT return type. 
Anything other return type make no sense and isn't valid C code anyway.

Actually you should enforce the entire definition of main.
I.e. only allow 0 or 2 arguments and if there are 2 arguments they must be type 
INT and CharPtrPtr.
