Description (partial)

Symptoms: A Cisco ASR 1000 crashes after the Segment Switch Manager (SSM)
 reports that an invalid segment has been detected:
 %SW_MGR-3-INVALID_SEGMENT: Segment Switch Manager Error - Invalid segment - no
 segment class.
 The crash follows this message. 
 Conditions: The symptom is observed on a Cisco ASR 1002 that is running Cisco
 IOS Release 12.2(33)XND1. The crash is caused by a NULL pointer de-reference
following the "no segment class" error. The error itself is not fatal and the
crash should have been avoided.
