5 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ out-of-bounds pointer arithmetic: null pointer is a dangling pointer (it has no provenance)
7 = help: this indicates a bug in the program: it performed an invalid operation, and caused Undefined Behavior
8 = help: see https://doc.rust-lang.org/nightly/reference/behavior-considered-undefined.html for further information
