Just confirm, this particular backtrace is from notmuch 0.18, right?
because 0.19 should build / be-linked-against libnotmuch.so.4.

No, I don't think so, that's a defined part of the API.

The usual problem on *BSD some incompatibility between glibc and BSD's
interpretation of POSIX. OTOH I couldn't identify something like that
from the backtrace you included.

I would be curious if the Xapian test suite runs in your environment.

notmuch probably hasn't been very well tested against xapian 1.2.20,
since it was only release a few weeks ago, and isn't available widely
(or more precisely, in Debian) as binary packages.  Are you running that
on your linux box as well?
