When using -O3 to start simutrans, it load a little bit then got the "Segmentation fault" message. However re-emerge with -O2 it work fine. Reproducible: Always Steps to Reproduce: 1.set CFLAG to "-march=core2 -O3 -pipe" 2.emerge games-simulation/simutrans 3./usr/bin/games/simutrans 4.get Segmentation fault message and the game closed 5.set CFLAG to "-march=core2 -O2 -pipe" 6.emerge games-simulation/simutrans 7./usr/bin/games/simutrans 8.No problems Actual Results: should work with -O3 or be forced to use -O2 in ebuild emerge
