--- Comment #3 from Andrew Pinski  ---
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:
```
:11:8: error: template template argument has different template
parameters than its corresponding template template parameter
   11 | SS ss;
  |^
:6:1: note: too many template parameters in template template argument
6 | template typename TT = SSS>
  | ^~~~
:8:10: note: previous template template parameter is here
8 | template typename TT = S, typename T = int>
  |  ^~
```

But that error message seems wrong.

--- Comment #1 from Kirkezz  ---
I was experimenting with the template template parameters, and ICE occured.
