[New-bugs-announce] [issue3453] PyType_Ready doesn't ensure that all bases are ready

[Roger Upole]

New submission from Roger Upole <rupole at hotmail.com>:

If a type's tp_base has not been initialized yet, PyType_Ready calls 
itself for tp_base.  However, it doesn't do the same for members of 
tp_bases.  The inheritance determinations assume that all bases are 
ready, in particular that tp_mro is not null.
