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

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

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