[LLVMdev] Unable to schedule 'Dominator Tree Construction' required by 'Module Verifier'

[mondi]

I have a simple parser / JIT execution module which I recently split up into separate shared libraries.

Previously, and as a test case, I'd generate IR, and immediately reparse / execute it. Now, the execution step lives in a separate but linked shared library. As soon as this happened, this error start popping up:

Unable to schedule 'Dominator Tree Construction' required by 'Module Verifier'
Unable to schedule pass
UNREACHABLE executed at PassManager.cpp:1230!

I've reduced it to the bare minimum test case - parser + linked execution, and it fails as long as the execution code is run from a dylib.

This is with the latest SVN code, on OS X 10.8

Anyone else seen this behaviour? Hopefully I'm missing something obvious
