The following is properly rejected but the error message is bogus:

Error: Character-valued internal function 'assumed_len' at (1) must not be
assumed length

I tried to find an internal function, but all I see is a module procedure. (For
internal functions, assumed-length result values are also invalid.)

module funcs
   implicit none
contains
      function assumed_len(x)
         character(*) assumed_len
         integer, intent(in) :: x
      end function assumed_len
end module
