Yes, but not your system gcc, it's during the libgcc compilation, where newly-
built llvm-gcc is already used.

Noone is working on any solaris support right now, so any breakage is
definitely expected.If you try running the failing command
/tmp/mfs/2.8/build/./gcc/xgcc -B/tmp/mfs/2.8/build/./gcc/ ...
by hand in the correct directory, does it still crash if you add
-emit-llvm to the command line?(In reply to comment #2)

Unfortunately, with --emit-llvm I have the exact same error:

Probably ice is related to f128 stuff. At least this goes from the file name....(In reply to comment #4)

Will do. Thanks for the help!(In reply to comment #4)

This didn't seem to change anything:

I just realized that I didn't specify --disable-multilib and --disable-
bootstrap to configure. Just for kicks, I tried adding both. This leads the
build to fail differently:

</output>LLVM-GCC has reached its end of life as far as llvm.org releases go. Please migrate to Clang or DragonEgg when possible. The llvm-gcc SVN repo will still continue to exist, so additional patches can go into it if you so desire, but since we have no more releases of it coming, it doesn't make sense to track bugs for it anymore.
If this is a problem that still exists with clang or DragonEgg, please file a new bug to track it. Thanks!
