One error is about using deleted D::D() and explains why it is deleted, the other is about using deleted D::~D() and explains why it is deleted. Do you mean we shouldn't diagnose using deleted D::~D() when we already diagnosed some other special member (D::D() in that case)? ^ permalink raw reply [flat|nested] 5+ messages in thread
