      Description

        A customer is seeing a missing card-mark in the pre-gc verification
        phase of GC. Without verification, the application crashes during
        a random GC. No further data is available at the moment but the
        GC logs and the hs_error logs.

        The crash occurs with their application, and no targeted test case
        is available that we can use here to reproduce the problem.
        However, customer is willing to do some runs w/switches etc. to
        assist in debugging the issue since this affects their application.

        The crash happens with both hs16 and the latest hs17(b05), but
        only with compressed oops enabled.
        Crash happens with -XX:+UseSerialGC as well as with -Xint. See details in
        comments section.
