Scratching about to try and find any other reports.
There is something going on in https://tracker.zentyal.org/issues/3130 and a handful of their other bugs that looks similar. Zentyal is listed as a drop in replacement for a Microsoft Small Business Server so it sounds likely they it could include Samba. That was only generated from a search for "strlen () at ../sysdeps/x86_64/strlen.S:106 Samba" though so it could be unrelated.
A Samba bug also comes up for a later package https://bugzilla.samba.org/show_bug.cgi?id=11530 but reading that suggests the strlen search I am doing is too general to find more than general protection faults. So what would "E_md4hash (passwd= p16= entry= ) at ../libcli/auth/smbencrypt.c:78" turn up?
That is more hopeful. There is this post http://gathering.tweakers.net/forum/list_messages/1607613 that seems to relate to Ubuntu 14.04 as well and contains a similar segment of stack trace in it:

Someone else might do a better job of translating the page. I can only vaguely follow it but it seems to point to https://bugs.launchpad.net/ubuntu/+source/samba/+bug/916576 near the end. Bug #916576 was marked expired in 2013-01-02 but there are some diagnostic requests in there that I can attempt. It also suggests some relation to bug 913809 which lists a huge number of duplicates and two Samba bugs. The Samba bugs mentioned seemed to trail off as unreproducible.
I'll leave the related items there for now. I will set my smb.cong log level 5 and provide the output of `sudo testparm -s` as requested in Bug #916576 and leave it there for now.
