Does the patch posted here: > https://gcc.gnu.org/ml/gcc-patches/2018-12/msg01433.html > help? It does indeed. However, I didn't do a full bootstrap, but just reverted my workaround involving #pragma GCC diagnostic ignored "-Wtautological-compare", applied your patch and reran make && make check. The build completed with no changes in testsuite results except for the new testcase. Thanks. Rainer
