Please don't use "-march=native -mtune=native" when
reporting bugs since we have no idea what they are.

It happens for me compiling Firefox from trunk source on 32-bit Intel/Linux
using -march=core2, but this doesn't appear to be specific to an architecture.
I'm available for applying test patches to snapshot builds if GCC developers
aren't able to reproduce.

Based on this, I just did some manual bisecting. There appears to
be 3 patches added just before gcc-4.5.1-r1 was unmasked in portage:

20_all_gcc-4.5-fno-strict-overflow.patch
49_all_gcc-4.5-pr46491-kernel-miscompile.patch
90_all_gcc-4.5-graphite-ICE.patch

removal of all 3 resulted in a gcc that would compile cairo without ICE. 

I then dropped just the graphite-ICE patch. Result: successful compile
I then dropped just the pr46491-kernel-miscompile. Result: ICE
I then dropped just the fno-strict-overflow patch. Result: ICE

90_all_gcc-4.5-graphite-ICE.patch points to:

Please try the unmodified GCC 4.5.1.

fails with the unmodified 20101125 snapshot. I'm going to revert the patch I
found above and will report back in a little while on whether or not it solves
it in vanillla gcc.

Can the fix be applied to the branch before the 4.5.2 release? Seems like it's
low risk since probably not too many people are using Graphite options.
