Details of bug

This is a parallel issue of NGEET/fates#1271. Labeling with both FATES tags because I don't know what it will eventually require to fix.

Important details of your setup / configuration so we can reproduce the bug

It can be reproduced using the test ERI_Ld60.f45_f45_mg37.I2000Clm50FatesCruRsGs.derecho_intel.clm-Fates, which is the ERI version of an ERS test we already run as part of the fates suite.
