--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Generally, ensuring that -Wmaybe-uninitialized has no false positives is
NP-complete problem. We have since 2010 in tree-ssa-uninit.c an attempt to
handle the most common cases (predicate aware uninit), which has been improved
over time. I guess you can look at *.uninit pass verbose dumps
(-fdump-tree-uninit-details) to see why it failed in this case.
