The `alloc_error_handler` function is still unsafe, so we need a feature gate to enable it. The function receives a single argument: the `Layout` instance that was passed to `alloc` when the allocation failure occurred. There's nothing we can do to resolve that failure, so we just panic with a message that contains the `Layout` instance.

With this function, compilation errors should be fixed. Now we can use the allocation and collection types of `alloc`, for example we can use a [`Box`] to allocate a value on the heap: With this function, compilation errors should be fixed.
