 Creating an instance of NSString or NSArray, and then attempting to modify
 it, causes a crash in MacRuby 0.4 (built from source, revision 1541):

 {{{
 $ macirb
 irb(main):001:0> str = NSString.stringWithString 'a'
 => "a"
 irb(main):002:0> str << 'b'
 (irb):2: [BUG] Bus Error
 MacRuby version 0.4 (ruby 1.9.1) [universal-darwin9.5, x86_64]
 }}}

 {{{
 $ macirb
 irb(main):001:0> arr = NSArray.arrayWithObject 'a'
 => ["a"]
 irb(main):002:0> arr << 'b'
 /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/1.9.1/irb.rb:302:
 [BUG] Segmentation fault
 MacRuby version 0.4 (ruby 1.9.1) [universal-darwin9.5, x86_64]
 }}}

 (Yes, I know that NSString and NSArray are immutable types, but a bus
 error or segfault seems a bit harsh.)
