forrtl: severe (71): integer divide by zero

appears after the output featured

CO2condens: improved_ztcond= T
In co2condens:Tcond(P=1mb)= 136.2700 Lcond= 590000.0
acond,bcond,ccond 3.2372880E-04 7.3383721E-03 3.3921085E-04

in the reference case obtained by meso_install.sh (used to work fine with r1520)

setting up callcond = .false. in mesoscale.def "fixes" the problem
