Since approx 2.089.1 the following code causes the compiler to segfault
```
template segfaults(x* x)
{
}
```
```
tempseg.d(8): Error: variable `x` is used as a type
Segmentation fault (core dumped)
```
This is a result of 6ebafdcbddca5c6cb01082f062cf68e2bcf3c8c3 (https://github.com/dlang/dmd/pull/10450)
The segfault can be fixed easily but the code here stinks (i.e. the error message is inane).
