Does the bug look like the phantom one I found?
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/66166

Something like 
./dict.rb:316: [BUG] gc_sweep(): unknown data type 28

It could be GCC's fault. I was doing something heavily threaded too
(from 20 to 150+ threads) which opened lots of connections to a dictd
server and found that the problem would only happen when compiling with
gcc 3.2, and moreover only when targeting i386, but not sure on this
one, have forgotten :-)
