>Description:
Internal error with the following two-liner program,
compiled with optimization. Compiler output follows:

bug.c: In function `bar':
bug.c:6: Internal compiler error in `fixup_memory_subreg', at function.c:2630
Please submit a full bug report.
See <URL: http://www.gnu.org/software/gcc/faq.html#bugreport > for instructions.
>How-To-Repeat:
gcc -c -O bug.i

bug.i follows again because it's small:

# 1 "bug.c"
void bar(void)
{
short   r = 1, *s;

r = r * r;
s = &r;

}

>Fix:
None :) (remove optimization flags)
