--- Comment #17 from Sven Hesse <sven.hesse at drmccoy dot de> ---
I still get this with gcc 12.2.0 (Gentoo 12.2.0 p9), but only when compiling
with (at least with) -O1 -fsanitize=address, in addition to any warning flag
that enables -Wmaybe-uninitialized (like -Wall, -Wextra or -Wuninitialized).
-O0 and/or no ASan, and the offending code compiles cleanly without any
warnings. Somehow, the combination of enabling ASan and optimization (anything
> -O0, but not -Os) triggers it again, it seems?
I can observe this with the testcase attached here in this bug report.
