In the standard library in Rust before 1.52.0 the Zip implementation has a panic safety issue. It calls __iterator_get_unchecked() more than once for the same index when the underlying iterator panics (in certain conditions). This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.

Rust pre 1.52.0 Zip calls unchecked twice for the same index during panics, risking memory safety with trusted random access.
