When an event comes from IDispEventImpl, there's a crash in

HRESULT hRes = lock.Lock();
This is because _pAtlModule == 0, so the lock object is not
initialized properly.

It seems that I had to write & post this stupid question to
immediately realize what happened :).
IDispEventImpl is a part of the *host*, so _pAtlModule == 0 in the
host, not in the dll.
This means that the host *must* be an ATL project...

You don't need to redo your whole project. You just need an instance of =
CAtlModule. Add this to any source file:

class CDummyModule : public CAtlExeModuleT<CDummyModule> {};
CDummyModule _Module;
