[LLVMdev] All the passes (even the LLVMHello.so) fail at doFinalization()

[Tianyin Xu]

Hi all,

I find all my passes are all broken with LLVM 3.4. Then I tried out the
LLVMHello.so specified in the LLVM doc,
http://llvm.org/docs/WritingAnLLVMPass.html
and it also crashes.

It seems all the functions in the pass do work, but LLVM crashes in the
doFinalization() step.

Does anyone know this problem?

Thanks!
Tianyin
