Seeing one more of these openmptarget (clearly unrelated) failures

4: [ RUN      ] openmptarget.partitioning_by_vector
4: /var/jenkins/workspace/Kokkos/core/unit_test/TestExecSpacePartitioning.hpp:100: Failure
4: Expected equality of these values:
4:   sum1
4:     Which is: 7642095
4:   sum2
4:     Which is: 0
4: [  FAILED  ] openmptarget.partitioning_by_vector (0 ms)

The HIP-ROCm-5.2 build passed and I am willing to ignore the HIP-ROCm-5.6-C++20 timeout
