Hi Andreas,
Could you please help to share more information about how to trigger this
error? As you don't mentioned, I assume below error comes from X86 build. I
take below configuration but failed to reproduce.
mkdir __BUILD_X86 && cd __BUILD_X86
../configure --enable-language=c,c++ --enable-bootstrap --disable-multilib
--prefix=`pwd`/../__INSTALL_X86
make -j $(nproc) && make install
Pan
