Null pointer dereference on rust nightly

[Xenira]

Tests reveal, that we get a nullpointer dereference when using nightly. Stable is fine.

thread 'integration::array::array_works' panicked at tests/src/lib.rs:163:13:

Probably related to this rust-lang/rust#134424

Seems like we were iterating one item to much, which previously failed silently.
