--- Comment #5 from jcmvbkbc at gcc dot gnu.org --- (In reply to Martin Liška from comment #2) > Can't reproduce with x86_64-linux-gnu cross compiler: > > ../configure --enable-languages=c,c++ --disable-multilib > --disable-libsanitizer --prefix=/home/marxin/bin/gcc --disable-bootstrap > --target=xtensa-linux-gnu > > Can you help me how to reproduce? Sorry, my configure line for gcc that was failing was: ../gcc/configure --prefix=`pwd`/root --target=xtensa-buildroot-linux-uclibc --disable-shared --disable-libssp --disable-libisl --enable-languages=c CFLAGS='-O0 -g3' CXXFLAGS='-O0 -g3' And the exact gcc version was f8c733e861ce8ca30013c364b062c4aef5c1f78a or r251982 in the SVN. The rest I believe is in the bug report.
