I've uploaded the core dump to vert since I see at least one password in the dump. Thanks.

It could be that bug as previous since I've not updated since then, I don't think. Let me know if you need anything else.

Are you able to reproduce this crash? i.e. if I submit a change, can you confirm if the isuse was fixed or not?

Unlikely, I didn't create this one, not that I know of. I can check the logs to see what might have been happening at the time but I reduced logging recently since my files were getting huge.

What do you have for "lines per message" for security level 0 in SCFG?

The gdb backtrace is very helpful, btw. Much appreciated.

The output of "print *this" could be helpful here too.

It looks like it was via another dialup modem issue via sexpots.

Is this what you're after?

<code>

I'll upload the print *this to vert for you in a minute.

(gdb) print *this
No symbol "this" in current context.

No dice unfortunately.

Ah yes, you'd need to switch to stack frame 14 in that core dump for "*this" to be in scope. Type "frame 14" then "print *this" (that should work) and paste the results (may contain passwords) into a file and upload to vert. However, that's probably not needed for me to root-cause and resolve this issue. I see from the other response that you're allow 20-lines per message for level 0 users (right?) - so that should give me the info I need to figure this out, even without out "print *this".

This would be useful to know: after "frame 14", then "print strlen(buf)". It may not work because the heap is corrupted where buf is pointing, but worth a try.
Also, the value of this->cols (it'd be included in the "*this" value printed, if you can supply that) would be helpful to know.

(gdb) print this->cols
$2 = 80

I'm about to upload a file to vert for you.
