//! Simple demonstration that `panic_on_next_alloc` actually works.
//!
//! This example will panic when run - it is meant to verify that the
//! panic-on-next-allocation feature is working correctly.
//!
//! To run this example, enable the `panic_on_next_alloc` feature:
//! ```bash
//! cargo run --example panic_on_alloc_demo --features panic_on_next_alloc
//! ```
