[Samba] smbclient Version 4.13.2 Crashes on Fedora 33

Have been working this on the BackupPC users and Fedora mailing lists, 
but it's looking more like a general problem in Samba utility, 'smbclient.'

BackupPC is a backup server package that uses Samba, rsync, and other 
protocols to backup clients, including Windows PC's. Basically, it runs 
a command like this for a SMB backup of a PC:

/usr/bin/smbclient \\\\new-pelican\\C\$ -U backup -E -d 2 -c tarmode\ 
full -Tc -

Output is piped to BackupPC utilities that unpack and index the backup, 
and do other housekeeping

My backups have consistently failed since my upgrade to F33 (were 
working without problems for years before, and most recently on F32).

Looking closely, it appears 'smbclient' is crashing after passing 
exactly 47 files. (BackupPC then quits after data stops coming in.)

I've run this command at the command-line; it runs for a few seconds 
then reports a core dump. Gnome shell then prompted me to file a Fedora 
bugzilla, which I have done.

https://bugzilla.redhat.com/show_bug.cgi?id=1900232 "[abrt] 
samba-client: remove_do_list_queue_head(): smbclient killed by SIGSEGV")

(I can't seem to make this bug report publicly readable...)

Anybody have further suggestions, please?
