What about the following program:
--------------------test.c--------------
#include <stdio.h>
#include <stdlib.h>
void*a,*b;
main()
{ int i;
a=b=0;
i=a==b; i+=a!=b;
a=malloc(1); b=malloc(1);
i+=a>b; i+=a>=b; i+=a<b; i+=a<=b;
printf("%d\n",i);
return i;
}
---------------------------------------
Is this program *always* required to print or return "3"?
