Description

when running the analytical spinup with r7180 and with the soil parameters of ORCIDEE 3.0 (see ticket #736), the model crashes after 208 years on a rather big mass balance issue for PFT6.

There was a real problem. Negative increment pools where obtained when recalculating allocation. Fixing that issue revealed some inconsistencies with the target model precision (EPSILON vs min_stomate vs zero). Issues have been fixed in r7194.
