[tkoenig at gcc dot gnu dot org]

------- Additional Comments From tkoenig at gcc dot gnu dot org  2005-07-19 07:30 -------
This is probably invalid code.

ifort rejects this with

fortcom: Error: elem-char.f90, line 5: A CHARACTER function name must not be 
declared with an asterisk type-param-value (i.e., (LEN=*)) if the function is 
an internal function.   [FOO]
  elemental function foo(a)

No elemental function call necessary, it seems. (The *
is probably invalid for this).

Here is another case which exhibits the same behavior:

$ cat clen.f90
program main
  implicit none
  character(len=2) :: a
  a = 'xy'
  print *,fun(a)
contains
  function fun(arg)
    character(len=*) :: arg
    character(len=len(arg)) :: fun
    fun = 'xx'
  end function fun
end program main
$ gfortran clen.f90
clen.f90: In function 'MAIN__':
clen.f90:5: internal compiler error: in gfc_conv_function_call, at 
fortran/trans-expr.c:1106

We don't handle the specification expression in this case
(sym->ts.cl->length->expr_type is EXPR_FUNCTION).

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-09-18 20:27 -------
All of these are fixed in 4.1.0. Since 4.0.2 is the last 4.0 release before a 4.1.0 release will be made, 
4.0.2 and 4.0.1 were special releases for gfrotran.  4.0.3 should be a normal release for GCC and 
gfortran in that regressions are the only changes.
