------------------------------------+---------------------------------------
 When I try to mutate an NSMutableArray while iterating over it, the
 Objective-C runtime will throw an exception which the MacRuby VM does not
 catch and propagate as a Ruby exception which causes MacRuby to segfault.

 The following example will cause MacRuby to segfault because of the
 problem mentioned above:

         numbers = NSMutableArray.alloc.init
         numbers.addObjectsFromArray [1, 2]
         numbers.each { |number|
                 numbers << 10 unless number == 10
         }
