icpc 19.0.4.233 not working with MacOS XCode 10.3 (10G8): template errors

I'm getting compiler errors using icpc 19.0.4 on MacOS with XCode 10.3. The same code compiles fine with the xcode tools (g++, which is llvm 10.0.1) as well as standard Visual Studio 2017 on Windows. I'm just on a trial of the Intel compiler tools for now. I am using templates and tuples in the code (see the error below).

Compiler command line:

icpc -o Build/ofx-debug/math-prims.os -c -std=c++17 -g -mmacosx-version-min=10.11 -fPIC -DPROJECT=MarkyMark -DVER=0.1.0 -DVMAJ=0 -DVMIN=1 -DVPOINT=0 -DPORT=ofx -DVARIANT=debug -DPORT_OFX=1 -DSPDLOG_DEBUG_ON -DSPDLOG_TRACE_ON -DENABLE_UNIT_TESTS -Ispdlog/include -Icxxpool/src -Iinih -I/usr/local/Cellar/opencv/3.4.0_1/include Build/ofx-debug/math-prims.cxx

Errors start like this:
