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

Oh, you mean opt -disable-verify? Yes, it does eliminate the crashing... Do you know what's the problem, Eric?
