--- Comment #8 from Martin Liška <marxin at gcc dot gnu.org> ---
Started with r9-4558-g476a31b55b5471262.
Slightly modified test-case:
$ cat pr97812.c
char c;
int main() {
volatile short b = 4066;
unsigned d = b & 2305;
signed char e = d;
c = e ? : e;
if (!d)
__builtin_abort ();
return 0;
}
@Richi: You can reproduce that on needle machine (su mliska):
$ cd /tmp/
$ gcc pr97812.c -O2 -flto -fdump-tree-all -o a.out && ./a.out
Aborted (core dumped)
