Hello,
I run across a compilation crash in Linux (Ubuntu 18.04) occurring with both
```
clang version 13.0.1-++20220120110844+75e33f71c2da-1~exp1~20220120230854.66
clang version 14.0.0-++20220120091458+c10c74887875-1~exp1~20220120091605.248
```
I tried to reduce the code with `creduce` but got non zero result after the **Interestingness** test commands.
Only **gcc** (I am using version 11) is able to compile the code correctly, **MSVC** is failing as well. The code contains some variadic templates, with pointers to members, and static evaluations.
It's difficult to guess where is the real issue, as the new code stuff I introduced compiles fine on [godbolt](https://godbolt.org/z/fz7rcrvj4).
Based on the crash logs, it seems to happen in clang front end.
