No virtual with CCMutableArray's deconstructor function ?

Is it correct?

OK, we can add virtual keyword, but… do you have the requirement to inherit CCMutableArray?

no, i have not this requirement.

i afraid someone delete a CCMutableArray object as a CCObject object.
and, i dont know how about it be release in ‘autorelease’

Thanks for your suggestion! I fix it immediately
