Example that produces the assertion

When trying to add a CallGraphSCCPass as a required pass for a ModulePass, the
following assertion is raised:

opt: /.../llvm/lib/Analysis/IPA/CallGraphSCCPass.cpp:535: virtual void
llvm::CallGraphSCCPass::assignPassManager(llvm::PMStack&,
llvm::PassManagerType): Assertion `!PMS.empty() && "Unable to handle Call Graph
Pass"' failed.

I've attached an example file.

Since I'm not completely sure if this is a bug, I tried asking on the mailing
list (http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-October/043987.html)
first but didn't get any responses.
