When running rustc on my repo, which has an AST parameterized over an arbitrary type T, I get:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x0000000c
0x000bb46c in glue$copy$$g14$t1$P1 ()
(gdb) bt
0  0x000bb46c in glue$copy$$g14$t1$P1 ()
1  0x003026e0 in ?? ()

Even an empty source file passed to rustc triggers the error.

WONTFIX (not required for bootstrapping, also I think long since obsolete)

CStr Safety invariant & Harnesses for from_bytes_until_nul (rust-la…
82da845 
…ng#180)

Towards rust-lang#150 

### Changes
* Added a `CStr` Safety Invariant
* Added a harness for `from_bytes_until_nul`, the harness covers:
    * The input slice contains a single null byte at the end;
    * The input slice contains no null bytes;
    * The input slice contains intermediate null bytes

### Discussion
* [Safety invariant
implementation](model-checking#150 (comment))
* [Input array
generation](model-checking#181)

### Verification Result
`./scripts/run-kani.sh --kani-args --harness ffi::c_str::verify`

```
// array size 16
Checking harness ffi::c_str::verify::check_from_bytes_until_nul...

VERIFICATION RESULT:
 ** 0 of 140 failed (5 unreachable)

VERIFICATION:- SUCCESSFUL
Verification Time: 7.3023376s

Complete - 1 successfully verified harnesses, 0 failures, 1 total.
