In my case, I hit a segfault in PassInfo::isAnalysisGroup() after PassManager.add(myModulePass) is called. My setup seems fairly simple, the attached code should reproduce the error.

Thanks for the response. I do have assertions enabled, and none of them are getting hit. I did do a search of the mailing list for the past year (approximately) before writing my email, and what I found was that you should be allowed to use LoopInfo and other analysis function passes from a module pass, with the only difference being that getAnalysis is passed the function. The example code I
