Yes, sorry, I mixed up my text snippets. The backtrace from notmuch 0.19
is analogous with the current libnotmuch referenced.

I'm not very familiar with neither notmuch, nor xapian. Where can I find
this test suite? Are you referring to the 'test' directory in the
notmuch tree? If so, I have the impression that a lot has to be patched
to make it run under FreeBSD (I get a myriad of errors when trying to
compile).

Yes, on linux I have the exact same version numbers of notmuch and all
dependencies (including xapian) and everything works fine.

The bug has already been reported on the freebsd bug tracker:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193809

I've referenced this thread there, hopefully the problem will get sorted
out. Would be a shame if such a nice email program remains only
partially functional on BSD.
