 Replying to [comment:32 rwbarton]:

 > Would you mind trying one more thing with LLVM 3.0 (with either the
 original or patched source tree)? Could you find the BuildFlavour stanza
 you are using in `mk/build.mk` (or just globally replace all of them if
 not sure) and change all occurrences of `-fllvm` to `-fllvm -fno-llvm-
 tbaa`? Curious if that would fix the issue.

 That did not appear to change anything for the better.

 I tried building the device (ARM) compiler with LLVM 3.4 but it failed. I
 suppose this is related to the info in comment:21. I'm trying now with the
 patch mentioned there.
