The last update was probably pre-wily.

That sounds like it's due to the GCC5/C++11 changes.  I wonder if you're
ending up using the xapian-core from vivid from the PPA (I'm not sure of
the timing, but guessing vivid was before that)?

I should put a newer version in the PPA and build it for wily too.  Will
sort that out soon.
