The file dawson.f90 from the numerical recipes library produces a segfault, in
reduced form:

!-------------- <snip> ----------------------------

        use nrutil

	FUNCTION dawsonseries_v(xin)
	IMPLICIT NONE
	REAL(SP) ::, DIMENSION(:), INTENT(IN) :: xin

	dawsonseries_v=1.0
	END FUNCTION dawsonseries_v

Of course we cannot compile this without the nrutil module.

I concur, but you don't need it in this reduced testcase (my fault for leaving
the statement there). Have a go at this:


        FUNCTION dawson_v(x)
        IMPLICIT NONE
        REAL, DIMENSION(:), INTENT(IN) :: x
        REAL, DIMENSION(size(x)) :: dawson_v
        dawson_v=1.0
        CONTAINS
!BL
        FUNCTION dawsonseries_v(xin)
        IMPLICIT NONE
        REAL, DIMENSION(:), INTENT(IN) :: xin
        REAL, DIMENSION(size(xin)) :: dawsonseries_v
        dawsonseries_v=1.0
        END FUNCTION dawsonseries_v
        END FUNCTION dawson_v

Confirmed, I think we are picking the wrong __result decl for the outer function (but I could be wrong, I 
have not looked at it much).

------- Comment #5 from pinskia at gcc dot gnu dot org  2006-01-02 04:00 -------
Also the following source fails in a slightly different way, an ICE in
fold_convert:
FUNCTION dawson_v()
  IMPLICIT NONE
  REAL  :: dawson_v
  dawson_v = 1.0

  CONTAINS
    FUNCTION dawsonseries_v()
      IMPLICIT NONE
      REAL, DIMENSION(1) :: dawsonseries_v
      dawsonseries_v=1.0
    END FUNCTION dawsonseries_v
END FUNCTION dawson_v

------- Comment #4 from pinskia at gcc dot gnu dot org  2006-01-02 03:59 -------
Reduced testcase which shows that the outer function does not have to return an
array to get the ICE:
FUNCTION dawson_v()
  IMPLICIT NONE
  REAL  :: dawson_v
  CONTAINS
    FUNCTION dawsonseries_v()
      IMPLICIT NONE
      REAL, DIMENSION(1) :: dawsonseries_v
      dawsonseries_v=1.0
    END FUNCTION dawsonseries_v
END FUNCTION dawson_v
