For example, I'm a bit curious on the following aspect. This program should
fail to compile on 32-bit platforms but succeed on 64-bit:
#include <stddef.h>
struct s { char a; long b; };
int main(int argc, char *argv[])
{
int array[offsetof(struct s, b) - 5];
return 0;
}
What happens if you run gcc -arch i386 -arch ppp64 on it? Does it require
success on both output architectures?
