[MacRuby-devel] hello world error

hi, it's been a while since i played with macruby, so i did a fresh install of 0.10 from binary om my 10.7 system and copied the hello world example from: https://github.com/mattetti/MacRuby--The-Definitive-Guide/blob/master/chapte... but running it and clicking the 'hello world' button prints an error: ~/Desktop/macruby$ macruby hello_world.rb Hello World! macruby(83412,0x10abe8000) malloc: *** auto malloc[83412]: error: GC operation on unregistered thread. Thread registered implicitly. Break on auto_zone_thread_registration_error() to debug. Otherwise things seem to work; the voice is there when you click the button. -Emil
