Segfault in rb_ary_push, ruby 1.8.4 (2005-12-24) [powerpc-openbsd3.8]

Hi,

I have a Ruby script that segfaults after a few days with:

  ./script/../lib/cardinal/handler.rb:30: [BUG] Segmentation fault
  ruby 1.8.4 (2005-12-24) [powerpc-openbsd3.8]

The line in question is:

29      def handles_response?(method)
30        public_methods.grep(method.to_s).first
31      end

A complete backtrace follows.  Hope this helps.  (I've not yet tried
to reproduce the bug in 1.8.5-preview1.)
