// This header exposes to Rust a C++ implementation of quickly crashing after an
// allocation error.  (The API below is called from `__rust_alloc_error_handler`
// in `lib.rs`.)
//
// TODO(lukasza): Investigate if we can delete this `.h` / `.cc` and just call
// `std::process::abort()` (or something else?) directly from `.rs`.  The main
// open question is how much we care about `NO_CODE_FOLDING`.
