Thanks for the test.  This has been fixed by 4631.

The bug was triggered by the auto-conversion of KinoSearch return values to
Perl elements when possible.  It became a segfault because Host_callback_obj,
which had previously been receiving a KinoSearch::Util::VArray, was now
getting a Perl array and was unprepared to handle it.

The fix was to reconvert the Perl array back to a VArray within
Host_callback_obj.  It might be somewhat inefficient, but it works.

None of them would have had an effect.  Unless you have been messing around
with Architecture or your code needs the recently removed SegReader method
get_doc_reader, upgrading to 4631 from 4625 should be no problem.
