--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I get the same ICE as H.J., and the bug is that redirect_all_calls
redirects a call to __builtin_unreachable , before it was
_10 = __open_alias (__path_6(D), __oflag_3(D), __builtin_va_arg_pack ());
and afterwards
__builtin_unreachable ("/dev/null", 3);
(note, again there is the bug that the extra arguments aren't dropped).
