commit    703cd9c31fd8f7224dd221eb1d860c4e28357bdb
Author:   Peter Eisentraut <peter_e@gmx.net>
Date:     Wed Aug 25 19:37:34 2010 +0000

    Catch null pointer returns from PyCObject_AsVoidPtr and PyCObject_FromVoidPtr
    
    This is reproducibly possible in Python 2.7 if the user turned
    PendingDeprecationWarning into an error, but it's theoretically also possible
    in earlier versions in case of exceptional conditions.
    
    backpatched to 8.0
