/* Output file size limit for files unpacked from unarchivers into RAM. Most
 * general archive compression formats can't nicely bound the output size
 * from their input filesize, and a cap is needed for a few reasons:
 *
 * - Linux is too dumb for its own good and its malloc/realloc will return
 *   pointers to RAM that doesn't exist instead of NULL. When these are used,
 *   it will kill the application instead of allowing it to fail gracefully.
 * - libFuzzer and the clang sanitizers have malloc/realloc interceptors that
 *   terminate with an error instead of returning NULL.
 *
 * Depackers that have better ways of bounding the output size can ignore this.
 * This value is fairly arbitrary and can be changed if needed.
