           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal

Created attachment 51061
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=3D51061&action=3Dedit
gzipped C++ source code

For the attached C++ code, recent gcc trunk with flag -Wall does this:

/home/dcb/gcc/results.20210626/bin/g++
mednafen/pce_fast/psg.cpp: In member function =E2=80=98void
PCEFast_PSG::RunChannel(int, int32)=E2=80=99:

        ../../trunk.git/gcc/toplev.c:327

        ../../trunk.git/gcc/cp/semantics.c:490

Code compiled fine with git hash 7dcf139a2b8e1c53, dated two days ago,
and goes wrong with 607c558804f70af2, dated yesterday.=
