• Status: RESOLVED FIXED

[Description Tsang Ka Wing 2009-11-21 08:27:28 UTC]

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
