It compiles OK, but segfaults when you run it. Also tried with gnubg-0.14.3 (just copied the ebuild + emerge digest), it does the same thing. When -ffast-math is removed, both 0.14.2 and 0.14.3 compile and run properly (except for a floating point exception when gnubg is asked for an evaluation, but that, I think, should be reported upstream). Reproducible: Always Steps to Reproduce: 1. Add -ffast-math to CFLAGS 2. emerge gnubg 3. run gnubg Actual Results: gnubg starts, shows a splash screen, and then segfaults before displaying the main window. Expected Results: games-board/gnubg-0.14.2 should filter -ffast-math from CFLAGS.
