It's not intuitive, although arguably conforms to the general C philosophy of not getting in the way unless the code has no chance of being right.
For example, both compilers do complain if you try to pass a literal NULL to `f1` (because that can't possibly be right), the same way they warn about division by a literal zero but give no warnings about dividing by a number that is not known to be nonzero.
