[cfe-dev] Cannot compile program when using the AnalysisManager

[Ted Kremenek]

Did you compile your entire project with -fno-rtti?  It smells like the linker is trying to find RTII information for BugReporterData, but it wasn't compiled in.  The LLVM libraries by default don't have RTTI information compiled in.
