This was around the time that the requirement to call DIBuilder::finalize() was added (and yes, I am calling it.) Specifically, what I am seeing is an assertion failure in llc because it can't find the compile unit for a subroutine.

I forgot to say earlier, that's a bug. Please file a PR with a test case.

I assume that the intent is that these references would be filled in later - but apparently this is not happening in my case. Any idea what could be wrong?
