     Type:  defect             |      Status:  new                  
 Priority:  critical           |   Milestone:  MacRuby 0.7          
Component:  MacRuby            |    Keywords:                       
-------------------------------+--------------------------------------------
 Running macrake without any argument results in a segmentation fault.
 Macrake also fails on trivial rake files with the same stack.

 It appears that object_getClass gets called with an invalid pointer (value
 8) by rb_objc_nsnumber2numeric.
