/**
 *    @file
 *          Stub implementations of the C++ ABI exception handling functions.
 *
 *    These functions replace the standard C++ exception code from the system's
 *    C++ runtime library with stub implementations that simply abort.  This
 *    reduces overall code size as well as eliminating some calls to malloc()
 *    that occur during global initialization (see the code in eh_alloc.cc).
 *    This provides significant memory savings on resource constrained devices
 *    that don't use exceptions.
