 }}}

 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.
