Description
The function TClass::GetListOfAllPublicDataMembers returns a TViewPubDataMembers. Issuing TViewPubDataMembers::FindObject("dm") should return the pointer to the datamember named "dm" if it exists as public data member in the class or its base classes, and 0 otherwise. However, it returns a seemingly random pointer to another data member in case of inherited public data members, and also for arbitrary arguments. On the command line:
% root -n
// load some class object
root [0] cl = gROOT->GetClass("TNamed") (TClass *) 0x1263640
// normal, expected behavior for data members (inherited from TObject):
root [1] cl->GetListOfAllPublicDataMembers()->FindObject("kIsOnHeap")
(TObject *) 0x1efd400
root [2] cl->GetListOfAllPublicDataMembers()>FindObject("kIsOnHeap")>GetName()
(const char *) "kIsOnHeap"
// wrong pointer returned (also from TObject):
root [3] cl->GetListOfAllPublicDataMembers()->FindObject("kZombie")
(TObject *) 0x1f08fc0
root [4] cl->GetListOfAllPublicDataMembers()>FindObject("kZombie")>GetName()
(const char *) "kNotDeleted"
// this should definitely return a nullptr:
root [5] cl->GetListOfAllPublicDataMembers()->FindObject("foo_bar")
(TObject *) 0x1f13fe0
root [6] cl->GetListOfAllPublicDataMembers()>FindObject("foo_bar")>GetName()
(const char *) "kNoContextMenu"
