Subject: Ruby 1.6.7 core dump

Hello;

I had a core dump with Ruby 1.6.7 (built from the RPMs at Caliban.org) and 
posted it at:

   http://www.soup-kitchen.net/bt.txt

My program evidently received a SIGPIPE for reading/writing from a 
one-ended pipe, but I assumed that my program would be insulated from this 
by IO.popen throwing an EOFException which I have a rescue clause for, and 
this worked 99.9% of the time.  The code is a fairly simple class which 
wraps the execution of a recursive wget process and returns URLs found for 
consumption by a matcher.  It's fairly short and posted at:

   http://www.soup-kitchen.net/fetch_wget.rb

This class was instantiated many times on many URLs and ran for several 
hours before my logs showed a Ruby segfault-- is this a problem with my 
code not catching SIGPIPE (which as far as I can tell, is meant to be 
ignored in signal.c) or should Ruby have just returned me an EOFError?

cheers,
