[ruby-core:39054] [Backport92 - Backport #4945] Segfault on Fiber#resume on Mac OS X 10.6.8

Issue #4945 has been updated by Christopher Bottaro.


I built Ruby-1.9.2-p290 patched with this commit:  https://github.com/ruby/ruby/commit/be953b4d1ce3f0dfc7f24c84ec7a51e027102557

and now I get the following:

=begin
$ bundle exec rake test
