Is it just me, or does mozilla break when things are compiled with -march=athlon-xp? I'm not sure what happens, but mozilla starts to load, a window flashes up briefly before mozilla quits. Running dbg on it says that it segfaults in WindowGetHeight() or some such function. When I recompile _everything_ back using -O -march=pentiumpro it works again. I'm sure I've compiled it for athlon-xp before on 5.0-RELEASE, has something changed to break it?
