What a great reduction, can you please share knowledge how did you achieve
that?!

--- Comment #10 from Alex Coplan ---
Reduced to:
int c = 1705;
char a;
long f = 50887638;
unsigned long long *h(unsigned long long *k, unsigned long long *l) {
return *k ? k : l;
}

long d = f;
for (char g = 0; g <

Can't repro with that seed (at least on aarch64-elf-gcc). I expect we're seeing
