mpp test failures with gcc 11

[rem1776]

Describe the bug
Two mpp tests fail on our development machines, test_mpp_checksum.3 (mixed prec checksum) and test_mpp_domains.14(check parallel). One fails on amd and the other on skylake

To Reproduce
make check with gcc 11.2.0 + mpich on the development machines

Expected behavior
tests should run successfully

System Environment
Describe the system environment, include:

• OS: centos
• Compiler: gcc
• MPICH
• netCDF Version: 4.8.0

mpp_checksum test failures are fixed with #1103. Domains still unresolved, only seems to happen on cent os 7 (skylake box).

[thomas-robinson]

The skylake box no longer exists. Can this be reproduced anywhere else?

Yeah the remaining test for this issue test_mpp_domains #14 is a common failure with other compilers as well. @laurenchilutti is working on it I believe.

[laurenchilutti]

yes, I am working on the test_mpp_domains check_parallel test failure - so this issue will be resolved with that fix.

[rem1776]

should be fixed with #1292, all mpp tests pass with gcc 11.4
