--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So, the problem is that we set CALL_FROM_THUNK_P:
378 if (current_function_decl && decl
379 && flag_new_inheriting_ctors
380 && DECL_INHERITED_CTOR (current_function_decl)
381 && (DECL_INHERITED_CTOR (current_function_decl)
382 == DECL_CLONED_FUNCTION (decl)))
383 /* Pass arguments directly to the inherited constructor. */
384 CALL_FROM_THUNK_P (function) = true;
on the Service::Service call in extends:extends inherited ctor, where the
second argument of current_function_decl is:
parm_decl 0x7fffefc50500 D.2359 type <record_type 0x7fffefc2bc78 xstring>
and the second argument of decl is:
parm_decl 0x7fffefc41980 name type <reference_type 0x7fffefc45a80>
The CALL_FROM_THUNK_P then prevents cp_genericize_r from actually transforming
the D.2359 parameter to *D.2359 that is needed after cp_genericize turned the
nameless D.2359 parameter into is_invisiref_parm.
I have no idea why call.c:384 sets the CALL_FROM_THUNK_P (is that for the case
that it can be called also when the DECL_INHERITED_CTOR (current_function_decl)
has invisiref parms replaced?
