Workaround for oneAPI internal compiler error

[manodeep]

Fixes the ICE for latest (?) oneAPI compilers. The applied fix worked for the latest version on gadi oneAPI/2024.2.1

Do not merge yet - need to confirm that the fix works for oneAPI 2025

@harshula You might already be setup to check whether this branch builds with oneAPI 2025 using spack.

(I have to fix the configure error with oneAPI first before I can get to the building stage)
