Subject:   A program that causes "bus error"

The following program causes "bus error" on a Sun workstation whether I
compile it with cc or gcc:

#include <stdio.h>
main()
{
	union { 
		char a[10]; int i;
	} u;
	int * p = (int *) &(u.a[1]);
	 * p = 17;
	printf("%d\n", *p);
}

However, it works fine (print out 17) on FreeBSD 3.2.  Can anyone explain
the difference for me?

Thanks a lot.
