The problem was due the introduction (in commit f3f0f13) of a fast path in TClass::GetListOfDataMember which did not take in consideration the case:

c = GetClass(someclassname)
c->GetState() == TClass::kForwardDeclared
c->GetListOfDataMember() -> list is now created but empty.
load and parse header file for
c->GetState() == TClass::kInterpreted
c->GetListOfDataMember() -> list is still empty but should have been filled (loaded at this point).

The logic assumed incorrectly that if someclassname was indeed pointing to a class or struct and the list was created then it was loaded.

To keep the fast path and correct the logic, we need to 'promote' TListOfDataMembers::fIsLoaded to be an std::atomic
