On the laptop, I tried issuing the "panic" command (within ddb), and got a core file, but the result appears to be a 'panic: from debugger', and the stack trace doesn't reflect the above, so it's not clear to me that that was a useful thing for me to have done. Is there some poking I can do to this to shed more light? Peace, david -- David H. Wolfskill da...@catwhisker.org The circus around that memo helps confirm that Mr. Trump is unfit for office.
