Description
Context
At the head of the trunk the ORCA2AGUL cases are failing with segmentation faults on our machine. Note that this is different to #1865 which is a compilation error when using TOP with AGRIF.
Analysis
The last successful test that I have run is at r7765 of the trunk. I'll run further tests at revisions in between to try to find the cause of the problem.

It turns out that my earlier test at r7765 wasn't compiled with LIM3. Compiling with LIM3 caused it to fail with a seg fault.
I've now discovered that the problem is due to issues in the setup of the ORCA2AGUL configuration. Specifically, the following changes are needed:
1) Copy namelist_ice_ref to 1_namelist_ice_ref
2) In 1_namelist_ice_cfg set nn_ice=3 (note that it used to be possible to set this to zero when using LIM2)
3) In 1_namelist_ice_cfg set ln_limini=.FALSE.
4) Set nn_fsbc=1 on both grids
5) Set nn_cln_update=1 in 1_namelist_cfg

- Resolution set to fixed
- Status changed from new to closed
Fixed in trunk at r7933
Further tests show that this has been broken since r7816. However r7816 was a bug fix for a compilation error introduced at r7788 so AGRIF can't be compiled in between these revisions.
