Phil, thanks for posting the link and patch.

Unfortunately, this patched version fails with segmentation faults when 
applied to 1.8.6-p230 and run against RSpec 1.1.4's test suite:

  lib/spec/example/example_group_methods.rb:384: [BUG] Segmentation 
fault

The 1.8.6-p111 version doesn't segfault.

Therefore, please consider another solution.
