# cat x.c
#include <stdlib.h>
struct a
{
unsigned int x[11];
};
unsigned long i;
struct a *c=( struct a*)0x3f736080UL, *b= (struct a*)0x1000048UL;
int
main()
{
i = (0x3f736080UL-0x1000048UL)/sizeof (struct a);
if (i != (c - b))
abort ();
return 0;
}
# gcc x.c
# ./a.out
zsh: 21264 abort ./a.out
Intel compiler works fine. Is this a really bad pointer bug?
