--- Comment #2 from Arsen Arsenović <arsen at gcc dot gnu.org> ---
unsure if this code is valid..
anyway, the crash reason is the lack of default in coroutine_handle. we pass a
NULL_TREE promise type to instantiate_coro_handle_for_promise_type in order to
instantiate the type-erased coro handle and the compiler gets confused:
/* We can also instantiate the void coroutine_handle<> */
void_coro_handle_type =
instantiate_coro_handle_for_promise_type (loc, NULL_TREE);
if (void_coro_handle_type == NULL_TREE)
return false;
passing void_type_note there fixes that crash and reveals another in
fold_builtin_call_array (so, it could be something else, I'll get back to that
later - I suspect (not too confidently) that it might be unrelated)
