--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I am not 100% sure this is valid or not; I suspect it is not valid but
MSVC looks like goes into an similar infinite recusion too.
While clang errors out:
```
<source>:11:8: error: template template argument has different template
parameters than its corresponding template template parameter
11 | SS<S, int> ss;
| ^
<source>:6:1: note: too many template parameters in template template argument
6 | template<typename T = int, template<typename> typename TT = SSS>
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<source>:8:10: note: previous template template parameter is here
8 | template<template<typename> typename TT = S, typename T = int>
| ^~~~~~~~~~~~~~~~~~
```
But that error message seems wrong.
