Library /sys$common/syshlp/dbg$help.hlb DEBUG, Messages, REGWRERR  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 unable to write/update register set, stack likely corrupted.

    Facility: DEBUG, VMS Debugger

    Explanation: Debug kernel failed to write/update the current
    context register set. Any pending deposits or steps may fail.
    Continuation in the presence of a corrupted stack typically
    results in unpredictable program and/or 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/or debugger behavior.
