[bug-mailutils] imap[s] seg fault in mail[x]

[Paul Vojta]

Folks:

I am getting a seg fault when running mail to access an imap folder.

Here is a short transcript:

| _xps> mail -f imaps://address@hidden
| Imap Passwd: 
| Segmentation fault

The segfault traceback (courtesy of gdb) is:

| #0  0x00007fe2cf55fcba in ?? () from /lib/libc.so.6
| #1  0x00007fe2d1933d6f in imap_parse (f_imap=0x23938c0) at folder.c:2440
| #2  0x00007fe2d1937067 in imap_messages_count (mailbox=0x23934d0, 
|     pnum=0x7fffda16a8e0) at mbox.c:699
| #3  0x00007fe2d1937389 in imap_scan0 (mailbox=0x0, msgno=1, pcount=0x0, 
|     notif=0) at mbox.c:740
| #4  0x000000000040c444 in main (argc=3, argv=0x7fffda16ab38) at mail.c:452

Here's a longer gdb session:

Comments, anyone?  How does one trace the imap connection?

Details are as before:

mailutils-2.0, Debian GNU/Linux unstable, x86_64.

        ./configure DEFAULT_CUPS_CONFDIR=/etc/cups --disable-mh-utils \
          --with-guiledir=/usr/share/guile/site --with-gnutls
