Implement #[alloc_error_handler] This to-be-stable attribute is equivalent to `#[lang = "oom"]`. It is required when using the alloc crate without the std crate. It is called by `handle_alloc_error`, which is in turned called by "infallible" allocations APIs such as `Vec::push`. 2018-07-06 15:49:52 +02:00			`// compile-flags:-C panic=abort`
