Re: [Mutt] #3074: Mutt hangs indefinitely

#3074: Mutt hangs indefinitely Comment (by jaymzh): I've now gone two days where I ran mutt with -d2 and it didn't hang. But if I start it up without it I can get a hang very quickly. Something about the debug code path seems to prevent it from hanging. I can try it with -d1 tomorrow, I gues

Re: [Mutt] #3074: Mutt hangs indefinitely

#3074: Mutt hangs indefinitely Comment (by brendan): It would be good to run mutt with -d2 and paste the last 10 or so lines of ~/.muttdebug0 (you may want to anonymize it a bit). There might be some clues there. -- Ticket URL:

Re: [Mutt] #3074: Mutt hangs indefinitely

#3074: Mutt hangs indefinitely Comment (by jaymzh): This most often happens on an unattended mutt (i.e. I'm in another virtual desktop for 10 minutes, come back, and it's frozen), so there's no resizing of the terminal. So a SIGWINCH is pretty odd. As for testing without SSL, not with my cur

Re: [Mutt] #3074: Mutt hangs indefinitely

#3074: Mutt hangs indefinitely Comment (by agriffis): In fact, if the problem could be the SIGWINCH then maybe jaymzh should switch to non-SSL for testing, to see if the bug can be repro'd without SSL in the picture. -- Ticket URL:

Re: [Mutt] #3074: Mutt hangs indefinitely

#3074: Mutt hangs indefinitely Comment (by agriffis): Why is mutt in crypto code while fetching message headers anyway? SSL? Also wondering what the SIGWINCH is doing there... terminal resized? That could account for the syscall being interrupted. Maybe the corruption happens while handlin
