Package: winbind
Version: 2:4.9.5+dfsg-5+deb10u1
I have Samba running with LDAP backend. Machine was installed freshly
with latest Buster, config copied and adapted from an old installation.
When running wbinfo -g, groups are listed as expected.
When running wbinfo -u, the winbind process crashes in
fill_domain_username_talloc, leaving the trace below with loglevel 10.

Yes, this seem to be exactly the issue there. Or there might be another
chance: memory pressure, so that talloc_strdup() returned NULL because it
was unable to allocate memory.. which has been also fixed in this place
by a later change:
https://gitlab.com/samba-team/devel/samba/commit/cbf312f02bc86f9325fb89f6f5441bc61fd3974f
I'm closing this bug report now with 4.16 version, where both fixes
are included.
Thanks,
