        PR middle-end/33382
        * tree-ssa-structalias.c (get_constraint_for_component_ref):
        Note that accesses to a whole flexible array member may not lead
        to a subvariable.

        * gcc.c-torture/compile/pr33382.c: New testcase.
        * gcc.c-torture/execute/pr33382.c: Likewise.
