Intel compiler trips up on ERF_advance_dycore

[ewquon]

This is NOT an ERF bug but documenting my experience here.

An Intel internal compiler error was observed for

• Intel(R) C Intel(R) 64 Compiler for applications running on Intel(R) 64, Version 19.0.5.281 Build 20190815
• Intel(R) C Intel(R) 64 Compiler for applications running on Intel(R) 64, Version 19.1.2.254 Build 20200623

when compiling RELEASE=RelWithDebInfo (i.e., -O2 -g)

My workaround was to compile TimeIntegration/ERF_advance_dycore.cpp with -O1; the remaining source files compiled without issue. Not sure if it is possible or makes sense to refactor this source file — or if this issue will be resolved with a future compiler version.
