--- Comment #16 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Can't reproduce the __builtin_unreachable on the trunk.
Bisection shows that
cc1plus -quiet -fsanitize=undefined -O3 -fwhole-program -fdump-tree-optimized
pr105469.C; grep unreachable pr105469.C.*
stopped printing anything with
r13-4686-g095a13eda2caf6842096a3ab78b2081c50fe8799
Martin, is that a real fix for this or it just went latent?
