### Details of bug

[Fill in details here.]

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

run f.e. ERI_Ld90.ne16pg3_ne16pg3_mg17.I2000Clm60Fates.derecho_gnu.clm-FatesCold

### Important output or errors that show the problem

TestStatus gives:

```
FAIL ERI_Ld90.ne16pg3_ne16pg3_mg17.I2000Clm60Fates.derecho_gnu.clm-FatesCold COMPARE_base_hybrid
```

TestStatus.log gives:
```

SUMMARY of cprnc:
A total number of 27 fields were compared
of which 8 had non-zero differences
and 0 had differences in fill patterns
and 0 had different dimension sizes
and 0 had different data types
A total number of 2 fields could not be analyzed
A total number of 0 time-varying fields on file 1 were not found on file 2.
A total number of 0 time-constant fields on file 1 were not found on file 2.
A total number of 0 time-varying fields on file 2 were not found on file 1.
A total number of 0 time-constant fields on file 2 were not found on file 1.
diff_test: the two files seem to be DIFFERENT

However, if you do:
```
grep RMS /glade/derecho/scratch/mvdebolskiy/ERI_Ld90.ne16pg3_ne16pg3_mg17.I2000Clm60Fates.derecho_gnu.clm-FatesCold.ne16icomp/run/ERI_Ld90.ne16pg3_ne16pg3_mg17.I2000Clm60Fates.derecho_gnu.clm-FatesCold.ne16icomp.mosart.h0a.2002-02.nc.base.cprnc.out
```
(because it was overwriten by comparison of `base` and `rest`)

If then you do `cprnc -m ` you get:
```
