Log of segmentation fault with stack trace

The server shares a local CUPS printer over SMB using samba.
Printing to the shared SMB printer causes the server's SMB daemon to segfault somewhere below here:

libsmbd-base-samba4.so(token_contains_name_in_list+0xfb)

Last known good version:
4.12.6

Known bad versions:
4.13.0
4.13.2

Built 4.13.2 [1] with the patch from bug 14568 [2] and it resolves this issue for me. It is a duplicate all right.
