Check if the backend properly handles aliasing here.  Likely

static tree
alpha_gimplify_va_arg_1 (tree type, tree base, tree offset,
                         gimple_seq *pre_p)
{
...
  ptr_type = build_pointer_type (type);

should be

  ptr_type = build_pointer_type_for_mode (type, ptr_mode, true);
