--- Comment #3 from Sunil Pandey <skpgkp1 at gmail dot com> ---
Seems like I hit the same bug with following test case. It appear during
GCompris and mednafen application build with GCC8.
$cat book.i.c
a;
char b[8];
c() {
int d = 0;
for (; d < 2; d++) {
b[d] = 5;
b[4 + d] = a >> d * 8;
}
}
$gcc --version
