This was helpful thanks. I do know how to use gdb, but hoping it won't
come to this. I was thinking of how to do that anyway. There must be
way to start dovecot (in gdb) so it does not fork and runs on a
non-standard port so I could configure the imap client to contact it on,
for example, port 1993. If someone knows how to do that, let me know.
gdb /usr/lib/dovecot/imap
r -u username
I tried what you said above. It seems to start IMAP running on stdin
connected to my username.
It's not clear to me how to debug this like that. Any recommendation?
In the client, I can easily set a different port like 1993. What I was
imagining was to start dovecot (or imap?) in gdb then connect with the
client, authenticate as myself, let it sync up it's folders, and then
watch the crash and poke around and try to print out the message and
folder.
Would it be easy for you to maybe print out the message and folder in
the assertion that is failing? Maybe this is easier for me to recompile
dovecot with that instead of trying to get into debug in the correct
child and all?
