--- Comment #8 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
Reduced:
trippels@gcc2-power8 ~ % cat namei.i
struct
{
int inode;
} * a;
int b, c;
void
fn1 ()
{
int d = 0;
while (b)
{
if (a->inode)
d++;
a = 0;
}
c = d - 1;
for (; c >= 0; c--)
;
}
trippels@gcc2-power8 ~ % gcc -O2 -fsanitize=undefined namei.i
gcc: internal compiler error: Segmentation fault (program cc1)
gdb backtrace looks identical to that from the testcase of PR63520 comment 11.
