    gcc/fortran/ChangeLog:

        PR fortran/83183
        PR fortran/86325
        * expr.c (class_allocatable, class_pointer, comp_allocatable,
        comp_pointer): New helpers.
        (component_initializer): Generate EXPR_NULL for allocatable or pointer
        components. Do not generate initializers for components within
BT_CLASS.
        Do not assign to comp->initializer.
        (gfc_generate_initializer): Use new helpers; move code to generate
        EXPR_NULL for class allocatable components into
component_initializer().
