--- Comment #5 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
Not sure if it's the same or a different crash. `systemd-258.1` ICEs on `gcc`
from `master` on:
```
long cpu_set_to_mask_string_c_0;
char cpu_set_to_mask_string() {
for (unsigned i = cpu_set_to_mask_string_c_0; i;)
for (int j = i % 2 ?: 2; j; j--)
({
long __cpu = --i;
__cpu;
});
return 0;
}
```
as:
$ gcc -O3 -c cpu-set-util.c.c -o bug.o
