includes latest ICE fixes from report about cairo ICE Reproducible: Always Steps to Reproduce:
I failed to reproduce this issue with 4.5.1-r1, but it was built on Tue Nov 23 22:15:25 2010 >>> sys-devel/gcc-4.5.1-r1
sorry for noise, I've rebuilt without graphite.
Created attachment 257002 [details] reduced testcase
hm 4.8.2 fails with ICE even w/o graphite flags. at least i can't compile it with # cat /etc/portage/env/dev-python/PyQt4 CFLAGS="-O2 -pipe -march=core2 -msse4.1" CXXFLAGS="${CFLAGS}
huh it seems settings flags in /etc/portage/env/dev-python/PyQt4 doesn't work for some reason for me. just tried to set them usual way in make.conf and PyQt4 compiled fine. So I can say PyQt4 is still broken with graphite flags even with gcc-4.5.2
Upstream isn't fixing this for 4.5 so there's not much to do unless you want to do the legwork.
