--- Comment #8 from Patrick patrick+winehq.org@laimbock.com --- (In reply to Patrick from comment #5)
Building wine-9.4 (without staging) without -Werror did not show the same error but when building with -Werror the build failed due to -Werror=stringop-overread in tools/winedump/msc.c and -Werror=maybe-uninitialized in tools/winedump/pe.c. See attachment.
I filed a separate bug: https://bugs.winehq.org/show_bug.cgi?id=56613
