As I understand, if SomeClass is in some dll, it will be there and be unique. If typeid(SomeClass) loads the symbol address from IAT, it will be the same address as in dll.
No, you don't understand. TypeInfos are stored in comdats. And they are only created if needed. So if you have SomeClass there is a typeinfo for SomeClass but not all possible typeinfos are created. Say you never use const(SomeClass) and then two other dlls use const(SomeClass) then each of those two dlls will contain a instance of the TypeInfo for const(SomeClass). This issue gets even worse with TypeInfos of templated types.
