David Seifert <soap at gentoo dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED Resolution|FIXED |--- --- Comment #13 from David Seifert <soap at gentoo dot org> --- The test case I gave wasn't the actual failure, because the actual failure still isn't fixed, I tried it with GCC 7.5. Do this to reproduce the real-world case: 1. clone https://github.com/jeffdaily/parasail/tree/develop 2. checkout the develop branch 3. autoreconf -vif 4. ./configure CFLAGS="-O3 -msse4.1" 5. The crash will occur in nw_stats_diag_sse41_128_64.c parasail doesn't have any dependencies other than zlib, so I think giving the real test case instead of running creduce multiple times might be more valuable.
