[LLVMdev] Strange LLVM Crash

[Nyx]

Valgrind seems to not like the Boehm's GC and cause a seg fault of its own
before I can even test anything.

Anyways, I don't see how I could be causing "memory corruption". If I do
something wrong, it has to be some kind of unintended use of the LLVM API.
I'm definitely not writing data into the LLVM function objects myself. Could
LLVM be deleting those objects is the question I'm basically asking.
