I have run into the same problem addressed in PR#170 on NCAR's cheyenne using the intel compiler with CESM. The compiler version is ifort (IFORT) 19.1.1.217 20200306. which sets the CPP macro __INTEL_COMPILER to 1910, and thus doesn't satisfy the condition currently specified, __INTEL_COMPILER >= 2021. Decreasing the compiler version in the conditional to 1910 allows us to run at our default optimization of O2. Running the unit test suit on cheyenne confirms both the failure and that the suggested patch works for us.
