error: Undefined Behavior: out-of-bounds pointer arithmetic: null pointer is a dangling pointer (it has no provenance)
--> RUSTLIB/core/src/ptr/mut_ptr.rs:LL:CC

LL | unsafe { intrinsics::offset(self, count) as *mut T }
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ out-of-bounds pointer arithmetic: null pointer is a dangling pointer (it has no provenance)
|
= help: this indicates a bug in the program: it performed an invalid operation, and caused Undefined Behavior
= help: see https://doc.rust-lang.org/nightly/reference/behavior-considered-undefined.html for further information
