Note that this problem only occurs if ln_bfrimp=.false. (i.e. not the usual case) because avmu and avmv are indeed set to zero in dynzdf_imp if ln_bfrimp=.true.. This a priori only concerns NEMO_3_6_STABLE. == Fix Extend masking of avmu/avmv in GLS from jpkm1 to jpk. ",Bug,closed,low,Unscheduled,OCE,v3.6,minor,wontfix,OPA v3.6,
