Hey guys,

I've been trying out ferret 0.9.3 on my powerbook this weekend and I've
been triggering 'bus errors' when using the Query API.  If I
programmatically build up strings, it works just fine.

There's some more information available in the trac ticket

Is anyone successfully using the Query API on mac os x?  Anything I can
do to help debug this?

Hi Michael,

I noticed in your code you are using BooleanQuery#add_clause method
but you are adding a query. Can you try BooleanQuery#add_query
instead? Let me know if that helps.

I attached a test case to this ticket that reproduces a bus error and
a segmentation fault on my macbook pro and another linux machine.

We were using ferret to help with our site navigation since the info
was already in the index and we wouldn't need to maintain a
denormalized table for the hierarchical data.  Ferret was called on
every page, sometimes multiple times per page.  This instability has
caused us to pull back on our use of ferret on the site.

Let me know if there's more information I can provide that would help.

Thanks Lee, I'm working on it.
