--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Auto has nothing to do with the problematic error message, take:
template<typename T>
struct A{};
A<tttt> x = A<short>();

GCC still produces:

<source>:4:13: error: cannot convert 'A<short int>' to 'int' in initialization
    4 | A<tttt> x = A<short>();
      |             ^~~~~~~~~~
      |             |
      |             A<short int>
