--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
for halt_on_error-1.c, it is trying to match:
WRITE of size 17 at 0x[0-9a-f]+.*READ of size 1 at 0x[0-9a-f]+.*WRITE of si=
ze 1
at 0x[0-9a-f]+.*READ of size 1 at 0x[0-9a-f]+.*


But we get just:
WRITE of size 17 at 0xffffffff8d60 tags: 01/00 (ptr/mem) in thread T0
...
