Looking for pointers to where to investigate more closely as I chase
this down.
Started getting repeatable mutt crashes, if I leave mutt running for a
while and come back to it; session is IMAP using Kerberos auth. Running
on FreeBSD, mutt built using Ports (poudriere). The crash is in
keymap.c. I can't recall when I started seeing this, but I only noticed
it in the last few days.
I rebuilt with debug enabled, to get a usable core dump, as before the
stack was garbage. There are patches, but when I grep in
/usr/ports/mail/mutt/files for files containing keymap, the only two
listed are not selected in my builds (neither sidebar-patch nor
signature menu).
The mutt version output is somewhat broken, I remember seeing this
before but don't recall the cause. Compiler is:
FreeBSD clang version 3.3 (tags/RELEASE_33/final 183502) 20130610
Mercurial tip shows no changes to keymap.c this year; a diff between the
keymap.c in the source used through the FreeBSD build and current
mercurial tip shows no diff: code is unmodified. Build uses ncurses.
The `struct keymap_t *` is non-NULL but every entry in it is zeroed out,
so in `map->keys[pos]` the `map->keys` part is NULL, thus a segfault.
What sorts of keymaps are allocated such that, after an idle time, the
memory might get blanked? Something allocated in an arena/pool/whatever
tied to the current connection?
Thanks,
-Phil
