The included file causes a segfault on gcc if the following compile options are used: g++ -march=athlon64 -O3 -pipe -c ArcEngine.ii -o ArcEngine.o Using -O2 also causes the segfault. -O1 don't. This is file is part of app-text/opensp-1.5.1 . This should problably be forwarded upstream (gcc shouldn't segfault). But gcc devs clearly state that: What we do not want * Bugs in releases or snapshots of GCC not issued by the GNU Project. Report them to whoever provided you with the release So I'm posting it here. Reproducible: Always Steps to Reproduce:

Just a correction. -O2 does not cause the bug. Only -O3.
`emerge info'? Is this with gcc-4.0.2 or gcc-4.0.2-r1? If the first one, please update and tell me if it is still a problem.

Just to make clear that the problem is happening on gcc-4.0.2-r1.
I will clean up the patch and get it into the patchset so the next time I bump gcc-4.0.2 it will be fixed. I'm leaving this open for now as a reminder to do this tomorrow :)
Added to the patchset. It'll be included next time I make a release.
The patch for this issue seems to cause another ICE. Reopening this for tracking purposes.
New patch in CVS to fix the regressions pr22252 caused. The new patch is from pr25010 and had some slight changes made to make it patch to 4.0.
Reopening because this patch is causing yet another issue.
bug #118361 is caused by this patch. I'm going to remove the two patches associated with this bug until upstream has a fix specifically for gcc-4.0, or someone else gets me a clean fix which doesn't make other problems appear.
Is there an upstream bug filled for this? If yes is there someplace where I can track its progress?
The upstream bug is in the URL field of this bug: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22252 Its currently fixed for gcc-4.1 and above. No idea if they plan on fixing it for the 4.0 branch.
