WAV/ICE coupling crashes upon restart

[mvertens]

Describe the bug
Running a configuration with wave/ice coupling - the model crashes upon restart.

It crashes in the following block of code:

    !
    ! 1.e Ice thickness interval
    !
    IF ( FLIC1 ) THEN
      IF ( TIC1(1) .GE. 0 ) THEN
        DTI10   = DSEC21 ( TIC1 , TI1 )
      ELSE
        DTI10   = 1.
      END IF
#ifdef W3_T
      WRITE (NDST,9015) DTI10
#endif
      IF ( DTI10 .LT. 0. ) THEN
        IF ( IAPROC .EQ. NAPERR ) WRITE (NDSE,1005)
        CALL EXTCDE ( 5 )
      END IF
    ELSE
      DTI10   = 0.
    END IF

Upon adding write statements it appears that TIC1 is not valid upon restart.
