Confirmed but not yet reduced.
I think this is caused by:
2004-03-21  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

        * alias.c (get_alias_set): Remove handling of PLACEHOLDER_EXPR.
        * emit-rtl.c (component_ref_for_mem_expr): Likewise.
        (set_mem_attributes_minus_bitpos): Call SUBSTITUTE_PLACEHOLDER_IN_EXPR.
        * explow.c (expr_size): Likewise.
        * expr.h (placeholder_list, find_placeholder): Deleted.
        * expr.c (store_constructor): Likewise.
        (get_inner_reference): Likewise.  Also don't call find_placeholder.
        (placeholder_list, find_placeholder): Deleted.
        (is_aligning_offset): Don't handle WITH_RECORD_EXPR, PLACEHOLDER_EXPR.
        (expand_expr_real, cases PLACEHOLDER_EXPR, WITH_RECORD_EXPR): Likewise.
        (highest_pow2_factor, case WITH_RECORD_EXPR): Remove.
        * dojump.c (do_jump, case WITH_RECORD_EXPR): Likewise.
        * dwarf2out.c (loc_descriptor_from_tree, case WITH_RECORD_EXPR):
        Likewise.
        * fold-const.c (invert_truthvalue, case WITH_RECORD_EXPR): Likewise.
        (extract_muldiv, case WITH_RECORD_EXPR): Likewise.
        * tree.c (expr_align, case WITH_RECORD_EXPR): Likewise.
        (contains_placeholder_p): Don't handle WITH_RECORD_EXPR.
        Clean up by using first_rtl_op.
        (substitute_in_expr): Use SUBSTITUTE_IN_EXPR for recursive call.
        (substitute_placeholder_in_expr): New function.
        * tree.def (WITH_RECORD_EXPR): Deleted.
        * tree.h (SUBSTITUTE_IN_EXPR, SUBSTITUTE_PLACEHOLDER_IN_EXPR): New.
