    Facility: DEBUG, VMS Debugger

    Explanation: The compiler-generated Debug Symbol Table for
    the specified module does not contain a valid version number
    identifier. The debugger is unable to determine if the Debug

    User Action: Submit an SPR to the compiler or assembler that was
    used to compile the module. Include the compiler version number
    and a sample source program which reproduces the error.
