        During testing with Tony's GC Test Suite, jbb2005 fails quite often with the following:

        # To suppress the following error report, specify this argument
        # after -XX: or in .hotspotrc: SuppressErrorAt=/ptrQueue.hpp:107
        #
        # A fatal error has been detected by the Java Runtime Environment:

        I've seen this most often on sparc/Solaris, but also on other architectures too (e.g., amd64).
