Yes. It allows application to run an atexit handler. Libgcrypt even
allows to register a dedicated handler: gcry_set_fatalerror_handler.
In any case the process needs to terminate as their is a fatal error
and something is going really wrong. Allow a process to continue is
not a good idea because it allows bugs to lurk around for years
without fixing. Such a bug is an indicator that something more severe
might have gone wrong.
