[reSIProcate] More Heap corruption..

[Byron Campen]

	I am not sure that is what you are seeing here. ContactRecord  
doesn't contain pointers to anything, and the ContactRecordList uses  
ContactRecord values (not pointers), so copy constructing the  
ContactRecordList mContacts should make full copies of everything  
(unless the copy constructor for Uri is broken somehow, which would  
be very surprising indeed). There should be nothing shared between  
the returned list and the list that is internal to the  
RegistrationPersistenceManager. Are you using the  
InMemoryRegistrationDatabase found in dum, or some other  
implementation of RegistrationPersistenceManager?

Best regards,
Byron Campen
