Yeah, you'd think so. The trouble is, to the compiler, it's just a
structure sub-pointer assignment -- the fact that the value at the
pointer is a function, that may eventually be called, is incidental.
Since pointers can in theory be cast, the most the compiler is willing
to do here is warn. (Maybe there's some setting to tell it to be
stricter about this, I don't know.)
