For completeness, compiles without variable "g" :

$ cat z3.f90
module m
contains
   function f()
      f = 1
   entry g()
      g = 2
   end
end

$ gfortran-7-20161009 -O0 -c z3.f90



Problem detected with variable named "f" :

$ cat z4.f90
module m
   real f
contains
   function f()
      f = 1
   entry g()
      g = 2
   end
end

$ gfortran-7-20161009 -O0 -c z4.f90
z4.f90:4:13:

z4.f90:2:9:

    real f
         2
z4.f90:4:13:

    function f()
             1
Error: Procedure 'f' at (1) has an explicit interface and must not have
attributes declared at (2)
