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

I just follow the tutorial: http://llvm.org/docs/WritingAnLLVMPass.html

Actually it's not only my module, I used the LLVMHello.so (a sample module
in the source tree) and get the crash (I didn't do anything :-P).

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

That doesn't tell me where your module came from. How did you create
the module that you're attempting to verify?

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

The module is shipped with the source code, so it's from the developers
(not me).

The path in the source tree is:
llvm-3.4.2.src/lib/Transforms/Hello

After compiled LLVM

*#./configure --prefix=XXX
--with-binutils-include=/path-to-binutils-2.24/include
--enable-debug-symbols --enable-debug-runtime --enable-assertions
--disable-optimized; make; make install*

LLVMHello.so is generated at llvm-3.4.2.src/Debug+Asserts/lib

According to the tutorial, the following command should be called to invoke
it,

#opt -load ../../../Debug+Asserts/lib/Hello.so -hello < hello.bc >
/dev/null

(and verify will be invoked by default).
