See RUST-141600: this test is broken in two ways: 1. This test triggers `-Wincompatible-pointer-types` on GCC 14. 2. This test requires ARMv8.5+ w/ MTE extensions enabled, but GHA CI runner hardware do not have this enabled.

//! Tests that MTE tags and values stored in the top byte of a pointer (TBI) are preserved across

//! FFI boundaries (C <-> Rust). This test does not require MTE: whilst the test will use MTE if

|
//! available, if it is not, arbitrary tag bits are set using TBI.
