Shell log:

$ cat t14.c
int main() {
        char a,b;
        asm volatile ("mov%z0 %1, %0" : "=r"(a) : "m"(b));
}
$ gcc -o t14 t14.c
t14.c: In function `main':
t14.c:4: internal compiler error: in print_operand, at config/i386/i386.c:7392

The same works if a and b are int. I also see this bug with GCC 3.3.5 on
i486-linux host/target.
