...I should have! (Never mind!) However, I have got the following results building with GCC 4.5.1: gcc -O3 Works fine gcc -march=barcelona Works fine gcc -O2 -march=barcelona -fgcse-after-reload -finline-functions -fipa_cp_clone -fpredictive-commoning -ftree-pre-partial-partial -ftree-vectorize -funswitch-loops Works fine gcc -O3 -march=barcelona explorer crashes out (three times?) rundll32 crashes out winecfg loads gcc -O3 -march=barcelona basically breaks something badly. I'm not sure if Wine should support -march or what the policy is, or if this is even a Wine bug, so I thought I would po...
