There are missing allocations in the sbcblk_core.F90 module which causes crashes at run time. Lines 166-169 in the following code must be added. (jf is aleady declared)

Jean-Marc PS : by the way : no means to set nemo_v3 version on the trac interface

    160          ! set sf structure
    161          ALLOCATE( sf(jpfld), STAT=ierror )
    162          IF( ierror > 0 ) THEN
    163             CALL ctl_stop( 'sbc_blk_core: unable to allocate sf structure' )   ;   RETURN
    164          ENDIF
    165
    166          DO jf= 1, jpfld
    167             ALLOCATE( sf(jf)%fnow(jpi,jpj) )
    168             ALLOCATE( sf(jf)%fdta(jpi,jpj,2) )
    169          END DO
    170
    171          ! fill sf with slf_i and control print

reported by Clement Bricaud:
When using non-climatological files, if we need to read the last record of previous year(month) in another file, there is a bug: we read the last reacord of the current year(month) file instead of the previous one.
For ex, when starting a run, with daily forcing, on Jan 1st of year 2008, we need 2007 Dec 31st but we will read 2008 Dec 31st.
Solution:
in fld_init, in the definition of llprevmth and llprevyr, replace "sdjf%ln_clim" by ".NOT. sdjf%ln_clim"

The expression "&namicethd" is written twice in the namelist_ice : https://forge.ipsl.jussieu.fr/nemo/browser/tags/nemo_v3/CONFIG/ORCA2_LIM/EXP00/namelist_ice_lim2 That doesn't make the model crash but the values and the variables of the block "namicethd" of the namelist_ice are not read. Hopefully, the default values in the namelist_ice file are the same than the values used to initialize these variables in the model. There is a problem only when you want to change one of these values by modifiying the namelist_ice : your modification is not taken into account in the model.
