segmented string was stored incorrectly

  Explanation:  The database  has  a  storage  map  for  segmented
  strings.   The  database has stored part of the segmented string
  in the incorrect area.

  User Action:  Currently this is only expected to happen when the
  RDML  or  RDBPRE  pre-compilers  are in use and the logical name
  RDMS$BIND_SEGMENTED_STRING_BUFFER has not been  specified  to  a
  large  enough  value to permit buffering of the entire segmented
  string.
