Steps to Reproduce

Install the oneapi C compiler, per the instructions at https://www.intel.com/content/www/us/en/docs/oneapi/installation-guide-linux/2024-1/apt.html then:

$ ./Configure -des -Dusedevel -Dcc=/opt/intel/oneapi/compiler/2024.1/bin/icx -Dusethreads -DDEBUGGING && TEST_JOBS=3 make -j3 test_harness

I suspect this needs a hints update, since these seem to be mostly floating point issues.

I tried using -mp which the hints add for the icc classic intel compiler, but icx doesn't accept this switch.

Expected behavior

All tests pass.
