--- Comment #6 from David Binderman <dcb314 at hotmail dot com> ---
I see very similar for this legal C code:
int li_4, li_5, us_8;
unsigned char func_7_ptr_13, func_7_uc_14;
void func_7_ptr_18() {
if (li_5) {
for (;;)
;
short s_15;
for (; func_7_uc_14;) {
us_8 = 7;
for (; us_8; us_8 += 1)
lblD2AF1FAB:
if (us_8)
li_4 = 1;
func_7_uc_14 += func_7_ptr_18;
if (func_7_ptr_13 & 1 && (func_7_uc_14 &= func_7_ptr_13))
s_15 %= func_7_uc_10li_19(s_15);
}
}
goto lblD2AF1FAB;
}
when compiled as follows:
$ ~/gcc/results//bin/gcc -c -O2 -Wall bug876.c
bug876.c: In function ‘func_7_ptr_18’:
