 WARNING: stack corrupted; session integrity not guaranteed

    Facility: DEBUG, VMS Debugger

    Explanation: While walking the call stack, the debugger has
    determined that the stack has been corrupted. It did however,
    find some valid call frames and will attempt to continue with
    that information. Continuation in the presence of a corrupted
    stack typically results in unpredictable program and debugger
    behavior.

    User Action: Look at what little valid information is left and
    then start over. Attempt to find and fix the point where the
    stack gets corrupted. It may be possible to examine program
    state, but continuing instruction execution typically results
    in unpredictable program and debugger behavior.
