What were you trying to do?
Exit discuss by typing q at the discuss: prompt
I had previously Ctrl-C'd through ckm since a few meetings
at the bottom of my .meetings file were on a downed machine
What's wrong:
It exited with a segfault and a core dump
What should have happened:
Neither the segfault nor the core dump should have occurred
Please describe any relevant documentation references:
This is more of a "for the record" bug, since I haven't been
able to reproduce it. I have had this problem in a few similar
situations (never consistently though), when I didn't have the
presence of mind to do anything other than rm the core dump
I copied my current .meetings file, identical to the one in
OldFiles, in /mit/aatharuv/for_bugs/.meetings . My core file
has been placed in a subdirectory of that, Private which I can
make accessible to anyone who might want to look into it.
