## Message

```
C pointer slices are no longer allowzero (#4462)

* Slices from C pointers are no longer allowzero but instead insert a runtime assertion.

* Added a test, fixed code for cases with non-allowzero C pointers

* Create new type when flipping allow_zero, sometimes we get a cached value back from adjust_ptr_len.

* Added comments, changed panic message

* Added runtime safety test.


```
