In addtion to this firefox (and libxul - same fix applies) problem, I
also ran into problems with:
multimedia/libxine PR 187017 already fixed
multimedia/gstreamer-ffmpeg PR 187018 already fixed
math/atlas PR 186997 i386 only / patch in PR
math/fftw* PR 186998 i386 only / patch in PR
These are not clang bugs, but differences from gcc.
Also, not a clang bug, but caused by the lack of gcc in base:
graphics/jogl PR 187186 patch in PR
I also ran into a problem bulding math/py-numeric for i386 on a machine
with an Athlon 64 CPU, which causes -march=athlon64 to be set. In this
case clang aborts. I filed this bug bug report upstream:
<http://llvm.org/bugs/show_bug.cgi?id=19029>.
I ran into a few more broken ports, but the problems are not clang
related.
