           Summary: Requiring a ModulePass and InstructionNamerID causes
                    PassManager to infloop

                    October/018091.html
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org

To reproduce:
* using LLVM TOT, unarchive the attached Hello.zip in lib/Transforms/Hello
* run make
* ../../../Release/bin/opt -load ../../../Release/lib/LLVMHello.so -tstfunc
foo.bc

foo.bc can be any bitcode

If I make the modulepass be a functionpass it no longer infloops, or if I
remove the InstructionNamerID from the requierements.

Stacktrace below:

Program received signal SIGINT, Interrupt.
