--- Comment #24 from Richard Biener <rguenth at gcc dot gnu.org> ---
The bug wasn't about uninit diagnostics with ASAN but without.  There are
plenty of diagnostic "bugs" when sanitizing is enabled and those are really
hard to fix since plenty of diagnostics rely on optimization to avoid false
positives which ASAN and friends prohibit.
