Ok, I can confirm the crash at build time when I force Mountain Lion to use clang anyway.

I also produced a crash at build time on Lion with Xcode 4.3.3, which uses clang by default. The Lion buildbot also crashed at build time. Building with llvm-gcc-4.2 was fine.

I also produced a crash at build time if I force my Snow Leopard machine with Xcode 3.2.6 to use clang. Building normally (with gcc-4.2) was fine.

So I changed it to just blacklist clang entirely in r97582.
