Here's a reduced testcase.

module test_mod

  implicit none

  contains

  function func1()
    real func1
    func1 = func2
  end function func1

  function func2()
    real func2
    func2 = 1 
  end function func2

end module test_mod

Note, if func2 is moved above func1 in the file, then we get
the expected error.

foo.f90:16.17:

    func1 = func2
                 1
Error: Function 'func2' requires an argument list at (1)


Also, note that the code compiles with 4.5.4 and 4.6.3,
so this is a regression.
