--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So it seems current_class_ptr is no longer just NULL or a PARM_DECL, but can be
also ADDR_EXPR of a PLACEHOLDER_EXPR.  Dunno if the right fix is
just
 bool
 parsing_nsdmi (void)
 {
   /* We recognize NSDMI context by the context-less 'this' pointer set up
      by the function above.  */
-   if (current_class_ptr && DECL_CONTEXT (current_class_ptr) == NULL_TREE)
+   if (current_class_ptr
+       && TREE_CODE (current_class_ptr) == PARM_DECL
+       && DECL_CONTEXT (current_class_ptr) == NULL_TREE)
     return true;
   return false;
 }
or something different.
