Hi Satoshi-san,
I have problems reproducing the defect.
Here is the code I used:
<<<
require 'osx/cocoa'
OSX.require_framework 'WebKit'
include OSX
3000.times do |i|
obj = NSObject.alloc.init
if obj.class.name != 'OSX::NSObject'
puts "Not NSObject at: #{i}"
p obj
return
end
view = WebView.alloc.initWithFrame(NSZeroRect)
view.setPolicyDelegate(self)
view.mainFrame.loadHTMLString_baseURL('<html></html>', nil)
end
puts 'No problem'
>>>
It always prints "No problem" on 2 different environments (ppc and
i386). I also tried to increase 3000 by a bigger number, without
success.
# I also try your AllocDefect projet, without success too :(
