  * Hat bug: 12-char prefix truncated from PackedString.
    * The definition of _tprim_unpackPS was calculating the wrong offset
      for the beginning of the byte array.
    * It also gave an invalid SR value to the trace for the resulting
      list of chars.
    * Finally, fixed a segfault with a NULL SR passed as argument to dumpSR.
