Confirmed.
2289 conversion *t = implicit_conversion (parmtype, argtype, arg,
2290 /*c_cast_p=*/false, flags,
complain);
2291 t->this_p = this_p;
2292 return t;
2293 }
2294
2295 /* Create an overload candidate for the function or method FN called
(gdb) p t
$1 = (conversion *) 0x0
note I'm not sure the particular error is very helpful. Why do we even
support asm("...") on aggregate types?
