Build with the Intel Classic Compilers 2021.6.0 and openmpi/4.1.5 fails ptest.

[Low, John J.]

To Whom It May Concern:

I have built pnetcdf 1.14.0 with the Intel Classic Compilers 2021.6.0 and openmpi/4.1.5 on Argonne's Improv Cluster<https://www.lcrc.anl.gov/systems/improv >.  It is a cluster of 825 nodes with two AMD EPYC 7713 64C 2GHz processors with an Infiniband HDR200 interconnect.

This build passes the serial tests but fails the parallel test invoked with the command "make ptests"

The third test in examples/C fails with the following error.

Error mmapping the file: Bad file descriptor

I have attached a config.log, output, and error.log from the failed test.

Any help in resolving this issue would be greatly appreciated.
