Does it help to update the rest of your system?
(In reply to comment #1) > Does it help to update the rest of your system? > Please get back to us
The bug is so rare, so I can't say it was definitely fixed.
Happened again with mutt-1.5.20-r10, same backtrace. This somehow correlates with amount of activity besides mutt. make -j5 was running when crash happened.
please try mutt-1.5.20-r15, and tell me if it segfaults too.
... and run a memcheck or something. If it only happens under stress, it feels unlikely to me to be mutt.
Again with mail-client/mutt-1.5.21-r1 Now backtrace matches and the box is completely different, so it isn't hardware.
your backtrace from comment #0 doesn't match the code of 1.5.21-r1.

Again, what's common. Rare bug. Always happens when I quit mutt/mainblox closes. Always gmail/IMAP. Load doesn't matter, this time there was no load.
Hrpmh... How do I exact source code of the package to a directory?
This could be http://dev.mutt.org/trac/ticket/3288, for which the patches are included in 1.5.21-r3. Also http://dev.mutt.org/trac/ticket/3482
and it helps to know what hcache backend you use (Show your USE-flags)
Haven't seen this for a while with mutt-1.5.21-r12.
with -r12 being stable, assuming fixed then, thanks!
