How can we reproduce the crash? Please provide reproduction steps.
That would probably be really helpful... Sorry about that, here is a simple example that will cause the crash. {{{ %cat mr_rspec_crasher.rb describe "Foo" do it "should fail" do fail "booya" end end }}} run with: {{{ rspec mr_rspec_crasher.rb }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/1055#comment:5> MacRuby <http://macruby.org/>

I reproduce the crash locally. Looks like rspec is doing stuff inside a #at_exit proc that causes this crash.
