[MacRuby-devel] Fixing ext/json

[dan sinclair]

I've simplified the crash to happen outside of the JSON extension.

module Test
   class << self
     attr_accessor :foo
   end
end

Test.foo = "asdf"

unknown: [BUG] destination 0x100fe3fb0 isn't in the auto zone
MacRuby version 0.5 (ruby 1.9.0) [universal-darwin9.0, x86_64]
