yes, the system termination handling changed from RTEMS 4.10.  Now every 
terminating execution path (unexpected exception, exit(), etc.) should end up 
in _Internal_error_Occurred() which invokes the fatal error extensions.

The application can provide an initial extension to do application specific 
termination handling.

The default provided by the BSP is to call bsp_reset().
