invalid DMT pointer; internal linker or debugger error

    Facility: DEBUG, VMS Debugger

    Explanation: The debugger found that the pointer in the image
    header to the Debug Module Table (DMT) was invalid. The debugger
    will continue from this error trying to initialize based on the
    Debug Symbol Table (DST).

    User Action: Check that the image file hasn't been modified or
    corrupted in some way. If not, submit a Software Performance
    Report (SPR).
