        Description

        Hotspot can crash during error reporting while trying to determine if the top (youngest)
        stack frame is a Java or native frame. If the top frame is indeed a native frame and
        the frame pointer is not available or contains trash, os::is_first_C_frame can segv
        while attempting to dereference it.

        This problem was encountered during attempts to reproduce 6340753.
