--- Comment #9 from Tobias Burnus <burnus at gcc dot gnu.org> --- Regarding the -mx32 issue (comment 0 to comment 3), that should be fixed by the patch https://gcc.gnu.org/ml/gcc-patches/2020-01/msg01663.html The issue reported in comment 4 should be fixed by patch https://gcc.gnu.org/ml/gcc-patches/2020-01/msg01929.html [However, the latter patch should be already part of the patches used for building GCC-10 for Debian; hence, it is unclear why the error reported in comment 4 occurs, unless there is some hen or egg problem.]
