commit r9-8643-g2a0de88ccf2ecc6659b0f1e4580c1ce5cff976b3
Author: Thomas Koenig <tkoenig@gcc.gnu.org>

    Finalization depends on the expression, not on the component.

    This patch fixes a 8/9/10/11 regression, where finalized types
    were not finalized (and deallocated), which led to memory
    leaks.

            * class.c (finalize_component): Use expr->finalized instead of
            comp->finalized.
            * gfortran.h (gfc_component): Remove finalized member.
            (gfc_expr): Add it here instead.
