Bus error with QueryParser and Perl class

[webmasters]

I’m trying to use QueryParser with WildCardQuery/RegexpTermQuery. I  
have a subclass of QueryParser that overrides the make_term_query  
method to return a regexp query (a Perl subclass of Query). When I  
search for some words, it works fine, but with others it crashes (bus  
error). The attached script crashes during the search, but if I  
uncomment the ‘use KSx::Search::WildCardQuery’ it crashes while  
parsing the query. If I change the search term from ‘trog’ to  
‘philaret’, it works.

The index I’m using can be found at http://synodinresistance.org/tmp/index.zip 
.

BTW, I’m using rev. 4669.
