Thanks for your testing. And my feeling strongly suggests that
SASL will be the reason of the segmentation fault. I have detected some
OpenLDAP SASL related errors on 10.0-RELEASE in the past:

http://lists.freebsd.org/pipermail/freebsd-ports/2014-February/089516.html
https://forums.freebsd.org/viewtopic.php?f=5&t=44576

That error affected portmaster and is solved.

It might be helful to add an SASL hint and a reference to this thread
to PR188019 (http://www.freebsd.org/cgi/query-pr.cgi?pr=188019). This
could help the port maintainers. But I am afraid that I cannot add
comments on an open PR. What do you recommend on how to proceed?

Regards,
Peter
