Data shouldn't be used in reassembly:

RFC 1122:

         4.2.2.12  RST Segment: RFC-793 Section 3.4

            A TCP SHOULD allow a received RST segment to include data.

            DISCUSSION
                 It has been suggested that a RST segment could contain
                 ASCII text that encoded and explained the cause of the
                 RST.  No standard has yet been established for such
                 data.
