This happens because the application omitted a call to rte_timer_subsystem_init(), which leaves a pointer set to null in the timer library. This pointer is dereferenced in a check for validity of a timer data object, resulting in the segfault. This series fixes the validity check in the timer library, and adds the missing call to rte_timer_subsystem_init in the application.
