Bug Description

RFC 3095, section 5.11 states:
   Therefore, in the ROHC UDP profile, the compressor generates a 16-bit
   sequence number SN which increases by one for each packet received in
   the packet stream.

However in the ROHC library, the SN is not bounded:
     /* increase the SN every time we encode something */
      g_context->sn++;

This is wrong, SN must be in range [0 ; 0xffff].
