I attempted to change the user password of a logged in userid using samba-tool
on the PDC and this is what happened:

[root at smb4-2 ~ (master)]# samba-tool user password -U testuser
Password for [BROCKLEY\testuser]:
New Password:
Retype Password:
Bad talloc magic value - unknown value
INTERNAL ERROR: Signal 6 in pid 79543 (4.10.15)
If you are running a recent Samba version, and if you think this problem is not
yet fixed in the latest versions, please consider reporting this bug, see
smb_panic_default: PANIC (pid 79543): internal error
