The file dawson.f90 from the numerical recipes library produces a segfault, in
reduced form:
!-------------- <snip> ----------------------------
FUNCTION dawson_v(x)
use nrutil
IMPLICIT NONE
REAL(SP), DIMENSION(:), INTENT(IN) :: x
REAL(SP), DIMENSION(size(x)) :: dawson_v
dawson_v=1.0
CONTAINS
!BL
FUNCTION dawsonseries_v(xin)
IMPLICIT NONE
REAL(SP) ::, DIMENSION(:), INTENT(IN) :: xin
REAL(SP) ::, DIMENSION(size(xin)) :: dawsonseries_v
dawsonseries_v=1.0
END FUNCTION dawsonseries_v
END FUNCTION dawson_v
!-------------- </snip> ----------------------------

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).
