================
Comment at: clang/lib/Serialization/ASTReaderDecl.cpp:1790
+    // set fake one.
+    D->DefinitionData = DD;
   ReadCXXDefinitionData(*DD, D);
----------------
I think it would make sense to "claim" the definition more eagerly here, by also updating `Canon->DefinitionData` in this case, prior to reading the definition data (and in the case where we already have a canonical definition, pointing `D->DefinitionData` at that eagerly).
