Hello all,
On Linux/Debian/Trixie/x86-64
/usr/src/Lang/gcc contains the GCC trunk source tree (commit 2a8af97e3528f)
/usr/src/Lang/_GccTrunk is my build tree with configuration
usr/src/Lang/gcc/configure --enable-shared --enable-threads=posix
--with-default-libstdcxx-abi=new --enable-libstdcxx-backtrace
--disable-multilib --with-gcc-major-version-only --program-suffix=-trunk
--enable-cet --enable-checking=release --build=x86_64-linux-gnu
--host=x86_64-linux-gnu --target=x86_64-linux-gnu --enable-host-shared
--enable-languages=c,c++,jit,lto -with-tune=native --enable-plugins
--enable-libgdiagnostics CFLAGS='-O2 -g' CXXFLAGS='-O2 -g'
the build fails reproductibly at
