Bug ID: 56049
           Summary: Wine >= 9.0-rc1: 32+64 bit build with -march=znver1
                    broken (libtiff, regression, gcc-12.2.0, Debian-12)
           Product: Wine
           Version: 9.0-rc2
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: windowscodecs
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Compiling a combined 32+64 bit Wine with -march=znver1 is broken since at least
Wine-9.0-rc1.
Tested on Debian-12 (gcc-12.2.0). There seems to be a problem with libtiff.

I'm using the following commands to build Wine since years. They worked fine
with Wine <= 8.21.
(Wine source has been extracted to wine-*)

Please tell me if you think this is not a Wine regression, but a GCC bug. Then
I'll report it at GCC.

export PREFIX="${HOME}"/wine-build
export CFLAGS='-march=znver1'
mkdir 64; cd 64

../wine-*/configure CROSSCFLAGS="${CFLAGS}" --enable-win64 --prefix="${PREFIX}"
--disable-tests

make -j16
mkdir ../32; cd ../32

PKG_CONFIG_PATH="${PREFIX}"/lib/pkgconfig:/usr/lib/pkgconfig:/usr/lib/i386-linux-gnu/pkgconfig
../wine-*/configure CROSSCFLAGS="${CFLAGS}" --with-wine64=../64
--prefix="${PREFIX}" --libdir="${PREFIX}"/lib --disable-tests

make -j16 install
cd ../64; make install

Since Wine >= 9.0-rc1 I'm getting the following error in the final "cd ../64;
make install" command when using "-march=znver1".
