It might compile as C, but it shouldn't compile as C++, because it's trying
to call an int(*)() with a parameter, even though that function (that the
pointer is pointing to does not take any parameter.)
Perhaps if it were an int(*)(void*) and then you reinterpret-cast the
parameter in order to call it, then it would compile.
As for "runs correctly", I don't see how this "runs correctly". Unless you
mean an infinite recursion that does nothing "runs correctly".
