Can you identify the document that triggers the segfault?  I suspect  
this is tied to specific content, and that the problem lies somewhere  
in the Italian PolyAnalyzer.

I believe that indicates an attempt to free some memory that malloc  
doesn't know about, either because it's a double free, or because the  
pointer was, say, uninitialized and pointing at something random.

However, I can't tell from that where such a problem might be  
arising, so we will probably need to try to continue trying to  
isolate a section of code.  Was that the whole trace?

What has changed?  Is the content the same?

Presumably, the version of KinoSearch changed between then and now,  
right?

These issues are probably related.
