NSZeroSize Causes Abort

[alloye@…]

In r36, accessing NSZeroSize prior to creating an instance of NSSize causes the interpreter to abort with an assertion failure. This behavior is unexpected and breaks one of the examples in the MacRubyTutorial.

[~]: /usr/local/bin/irb --simple-prompt
>> framework 'Foundation'
=> true
>> point = NSPoint.new(0, 0)
=> #<NSPoint x=0.0 y=0.0>
>> rect = NSRect.new(point, NSZeroSize)
Assertion failed: (bs_boxed->ffi_type != NULL), function rb_bs_boxed_new_from_ocdata, file objc.m, line 532.
Abort trap

[~]: /usr/local/bin/irb --simple-prompt
>> framework 'Foundation'
=> true
>> point = NSPoint.new(0, 0)
=> #<NSPoint x=0.0 y=0.0>
>> size = NSSize.new(0, 0)
=> #<NSSize width=0.0 height=0.0>
>> rect = NSRect.new(point, NSZeroSize)
(irb):4: warning: already initialized constant NSZeroSize
