I think this is another case of this issue:

https://cplusplus.github.io/LWG/issue4109

The issue raises a genuine concern: int8_t may be an alias for char, and
thus giving UB (because char is not in the list).
But your case sounds way more theoretical. Is there a real-world
implementation where uint_fast32_t isn't one of the listed types?

Thank you,
