One common problem (the only one I really know about, unfortunately)
is trying to load a module into Xcode's copy of "opt" rather than one
from the same tree as your module.

Xcode's one comes from a separate branch and is almost certainly
ABI-incompatible with every single revision of the main LLVM tree, in
one way or another.

Cheers.

Tim.
