Comment(by dterei):

 OK so now I'm not sure what is causing these bugs.

 My own machine is very similar to yours. Latest generation 13" Macbook. So
 OS X 10.8.2, 64 bit. I can bootstrap GHC with LLVM 3.1 fine. As you said,
 for a lot of these tickets the LLVM version shouldn't matter, so I'm just
 not sure why you are getting these panics and I'm not. Especially as these
 panics are things I thought I had already dealt with 2 years ago... (as
 you've noted, there is code already in the backend to handle these cases,
 but it doesn't seem to trigger correctly on your machine but does fine on
 mine).

 If our machines were vastly different or you were cross compiling... argh!

 I'll look through your patches again then and try to see if I can figure
 anything out from them.

 Are you using homebrew on your machine?

 Hmmm... I don't have my OS X machine right now but I believe I may be
 using GHC 7.4.2. I'll check that and then try 7.6.1 if I'm indeed using
 7.4.2.
