CDO

Problem: I have some monthly values for certain variables for certain years, namely 2015, 2020, 2030, ..., 2100. I would like to use CDO to interpolate values for the missing dates with the interpolation conducted for each month (e.g., only consider January 2015 and 2020 data when interpolating values for January 2016). It is my understanding that -intyear performs this operation.

I have uploaded two small, representative netcdf files which produce the error on my system when I try a command like (filenames truncated for clarity):

cdo -intyear,2016,2017,2018,2019 file2015.nc file2020.nc outpattern
or
cdo -intyear,2016/2019/1 file2015.nc file2020.nc outpattern

I receive a segmentation fault. When I run the above commands with a verbose -v argument:
OpenMP: num_procs=1 max_threads=1
Segmentation fault (core dumped)

Now, I'm curious if this is idiosyncratic to my build of CDO (Harvard Cannon Cluster), if I'm doing something incorrectly, or if it's a bug. For what it's worth, I've tried using several different permutations of openmpi/mvapich2 and gcc/intel compilers with no change in behavior.

Is anyone able to reproduce this segfault with my datafiles?
