Bug #2330: Non systematic segmentation fault with autoload rubyspec
http://redmine.ruby-lang.org/issues/show/2330

Author: Marc-Andre Lafortune
Status: Open, Priority: Urgent
Assigned to: Yukihiro Matsumoto, Category: core, Target version: 1.9.2
ruby -v: ruby 1.9.2dev (2009-11-04 trunk 25641) [x86_64-darwin10.0.0]

Starting from r25601, the following rubyspec will crash about half of the time (just repeat a couple of times):

$ mspec -t rubydev core/kernel/autoload_spec.rb
ruby 1.9.2dev (2009-11-04 trunk 25641) [x86_64-darwin10.0.0]
.........../Users/work/mspec/lib/mspec/mocks/proxy.rb:8: [BUG] Segmentation fault
ruby 1.9.2dev (2009-11-04 trunk 25641) [x86_64-darwin10.0.0]
