Did you mean to add this FIXME?
================
Comment at: lib/Serialization/ASTReaderDecl.cpp:4246
OldDD && (OldDD->Definition != RD ||
!Reader.PendingFakeDefinitionData.count(OldDD));
RD->setParamDestroyedInCallee(Record.readInt());
----------------
This does not appear to be NFC: the `FakeLoaded` vs absent-from-map distinction
matters here. I think the idea here is that we still need to load the lexical
contents of the declaration of the class that we pick to be the definition even
if we've already found and merged another definition into it.
That said, if this //is// necessary, we should have some test coverage for it,
and based on this change not breaking any of our tests, we evidently don't. :(
I'll try this change out against our codebase and see if I can find a testcase.
