make[5]: *** [c/libfswatch.lo] Error 1

This was previously reported in #44726 where it was using clang-3.4, and the solution was to blacklist clang-3.4 and clang-3.3 and add clang-3.5 to the fallback, but now clang-3.5 is crashing as well.

Using clang-3.5 or later on OS X 10.8 or earlier is problematic because it forces the use of libc++.

I'll test with clang-3.6, but it'll take me awhile to build it.

Was a bug report ever filed with llvm, as the error message says to do? If not, that should be done. If there is a fix, it would be great to get it into llvm-3.4 at least so that libc++ is not required.

Thank you very much Ryan.

No, I did not file a bug report and I’m glad to do it now. By the way, how can I get the files I should attach to the bug report, as specified by the CLang error message:

Those files are on the automated build server, to which you don't have access (they get removed right after the automated build anyway). You would need to reproduce the failure on your own system (which might need to be a Snow Leopard system) and then attach the files from your own system.
