+//! Validates the correct behavior of writing a `bool` value using `std::ptr::write`.
+//!
+//! This test addresses historical concerns regarding the internal representation of `bool`
+//! (e.g., as `i1` in LLVM versus its byte-aligned memory layout) and checks that
+//! `ptr::write` correctly handles this type without issues, confirming its memory
+//! behavior is as expected.
