Out-of-bounds error when running with only Kessler and Kain-Fritsch schemes

[mgduda]

When running MPAS-Atmosphere in debug mode with only the Kessler and Kain-Fritsch schemes, i.e., with the following &physics namelist

&physics
    config_sst_update = false
    config_sstdiurn_update = false
    config_deepsoiltemp_update = false
    config_radtlw_interval = '00:30:00'
    config_radtsw_interval = '00:30:00'
    config_bucket_update = 'none'
    config_physics_suite = 'none'
    config_convection_scheme = 'cu_kain_fritsch'
    config_microp_scheme = 'mp_kessler'
/

an out-of-bounds memory error occurs in the phsyics_get_tend_work routine:
