--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This isn't reported since r12-3918-g5b8b1522e04adc20980f396571be1929a32d148a
I wonder what is the point of -O3 -fsanitize=undefined, -fsanitize= severely
slows down the code for instrumentation and at the same time you ask for as
many optimizations as possible.
