It's worth noting that `__attribute__((stdcall))` and `__stdcall` works just
fine.

--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The ICE part with additional -g is fixed on the trunk with PR106937
r13-3202-g67efffec9436 fix.
Even just:
--- gcc/c-family/c-pretty-print.cc
+++ gcc/c-family/c-pretty-print.cc
@@ -901,7 +901,7 @@ pp_c_attributes_display (c_pretty_printer *pp, tree a)

        }
-      pp_tree_identifier (pp, TREE_PURPOSE (a));

       if (TREE_VALUE (a))
        pp_c_call_argument_list (pp, TREE_VALUE (a));
     }
would prevent the ICE.
I can't reproduce any
