! PR 25217: INTENT(OUT) dummies of derived type with default initializers shall
! be (re)initialized upon procedure entry, unless they are ALLOCATABLE.
! Modified to take account of the regression, identified by Martin Tees
! http://gcc.gnu.org/ml/fortran/2006-08/msg00276.html and fixed with
! PR 28788.
