Comment (by scpmw):

 LLVM 3.2 isn't blacklisted, so I think we are still "supporting" it, at
 least on paper. The comment might be referring to #7694? It's quite
 possible that this is actually the fix for that issue - crashes at
 virtually random places sounds about right.

 All I can say is that after applying the patch I was able to run the full
 test suite using LLVM 3.2. Without it, we get at least a dozen segfaults
 in there.
