[Mutt] #2935: Occasional segfault when IMAP inbox updates



#2935: Occasional segfault when IMAP inbox updates

 Version: mutt-20070709[[BR]]
 Platform: Debian/etch on amd64

 I have an IMAP inbox that is updated asynchronously on a remote server.
 Sometimes, when new messages come in, and Mutt has uncommitted changes to
 the inbox, it segfaults.

 This is what it looks like in GDB:

 {{{
 Fetching message headers... 1899/1900
 Program received signal SIGSEGV, Segmentation fault.
 0x000000000044f25e in mx_update_context (ctx=0x7b15d0, new_messages=4)
     at mx.c:1566
 1566          h->security = crypt_query (h->content);
 (gdb) p h->content
 Cannot access memory at address 0x50
 (gdb)
 }}}

 I have two core dumps saved from these crashes, and so can return
 additional telemetry upon request.
