Xapian discuss - Sep 2009 - InvalidArgumentError throw using Turkish stemmer and posting text "'leri"

Hi all,
I've come across a very strange bug with Xapian 1.0.9.0 and the Turkish
query parser when trying to index a string (as posting) that looks like
this: "...bir araya getiren CD'leri son teknolojiyle piyasaya...".
The
actual offending bit of the string is:  'leri

It throws the message I have shown below. The real annoyance is that I can't
seem to catch it because it is thrown from the XS (is there any kind of
signal trap that might catch this?)

terminate called after throwing an instance of
'Xapian::InvalidArgumentError'
Aborted

I'm struggling to follow exactly what you're doing to cause this
exception.  I can successfully stem "'leri" with the Turkish
stemmer.

Can you post some actual code (ideally something self-contained)?

Upgrading would help if this is coming from Xapian::Document - 1.0.14.0
adds exception handling to methods of Xapian::Document.

This looks like an escaping error to me, where "leri son teknolojiyle
piyasaya..." is being parses as the 2nd argument to whatever function
you're using.
