----------------------------------+-----------------------------------------
 Running the following script will raise two 'instance variable __octype__
 not initialized' warnings after calls to CGPDFContextCreateWithURL and to
 CGContextShowGlyphsAtPoint even though the __octype__ variable is never
 explicitly used in the script.

 ---

 framework 'Cocoa'

 url = CFURLCreateWithFileSystemPath(nil, './my_pfd.pdf',
 KCFURLPOSIXPathStyle, 0)

 page_rectangle_pointer =
 Pointer.new_with_type('{CGRect={CGPoint=dd}{CGSize=dd}}')
 page_rectangle_pointer[0] = NSMakeRect(0,0,100,100)

 pdf_context = CGPDFContextCreateWithURL(url, page_rectangle_pointer, nil)

 CGPDFContextBeginPage(pdf_context, nil)

 CGContextSelectFont(pdf_context, "TimesNewRomanPSMT", 11.0,
 KCGEncodingMacRoman)
 CGContextSetCMYKFillColor(pdf_context, 0.0, 0.0, 0.0, 1.0, 1.0)

 string  = Pointer.new_with_type(:S, 4)[[BR]]
 string[0]       = 68[[BR]]
 string[1]       = 69[[BR]]
 string[2]       = 70[[BR]]
 string[3]       = 71[[BR]]

 CGContextShowGlyphsAtPoint(pdf_context, 25.0, 45.0, string, 4)

 CGPDFContextEndPage(pdf_context)
 CGPDFContextClose(pdf_context)

 ---

 Calling the script produces the following output :

 $ macruby -w cocoapdf.rb
 unknown: warning: instance variable __octype__ not initialized
 unknown: warning: instance variable __octype__ not initialized

 This is on 10.6.4 with MacRuby 0.7.1.
