Package: mutt
Version: 1.5.16-3
Severity: normal
>From time to time, mutt will crash with a SIGSEGV when doing an IMAP
mailbox check. I build an unstripped version of the package with
debugging symbols enabled to get better data.
Here's the backtrace:
(gdb) where
#0 mx_update_context (ctx=0x770130, new_messages=1) at ../mx.c:1669
#1 0x000000000048dd3d in imap_read_headers (idata=0x76fad0, msgbegin=35182,

The bit of code is here (line 1669):
1664 h = ctx->hdrs[msgno];
1665
1666 if (WithCrypto)
1667 {
1668 /* NOTE: this _must_ be done before the check for mailcap! */
1669 h->security = crypt_query (h->content);
1670 }
1671
1672 if (!ctx->pattern)
1673 {
h in this case is NULL (hence the SIGSEGV), as is ctx->hdrs[msgno].
msgno in this specific crash is 35182. ctx->msgcount is 35183. So this
is the last message.
ctx->hdrs[msgno-1] points to something real. This may end up being a
fencepost bug to me but I don't know enough about the mutt internals to
say where it is just yet.
I can't reproduce this at will but it occurs with some frequency (once
every couple of days or so with the mailbox I'm using). Mutt is talking
to dbmail (2.2.5-1) on the backend.
I've saved the core file just in case you need me to go back and look at
this.
