Confirmed, started with

Make canonical_va_list_type more strict

            PR C/71602
            * builtins.c (std_canonical_va_list_type): Strictly return non-null
for
            va_list type only.
            * config/i386/i386.c (ix86_canonical_va_list_type): Same.
            * gimplify.c (gimplify_va_arg_expr): Handle &va_list.

            * c-common.c (build_va_arg): Handle more strict
            targetm.canonical_va_list_type.  Replace first argument type error
with
            assert.

            * c-c++-common/va-arg-va-list-type.c: New test.
