I have code which does this, in a debugger which also offers some features which ddb doesn't have. Unfortunately, I trusted it to DDS tapes, with the result that I can't read the latest version. I've retrieved a version on ftp://ftp.lemis.com/pub/lowbug.tar.gz, but it's out of date in some respects. Still, it might be of use as a basis for new work. I note that the documentation includes a copy of the GPL. I can't recall why; I never placed the debugger under the GPL.
