We solved it at a global level years ago. If you look at WebPageProxy::didReceiveMessage() in generated code, you will see: auto protectedThis = makeRef(*this); We protect the WebPageProxy while calling every function due to an IPC message.

Comment on attachment 417198 [details] Patch r=me Smart pointer is definitely better than raw pointer here. Would be nice in the future just to make this lifetime mismatch impossible.
