Did you notice that AdaptiveCpp merged this PR recently? AdaptiveCpp/AdaptiveCpp#1452
I think this should add support for get_multi_ptr so this fix may not be needed anymore.

Thank you for pointing that!
I see that they have not updated the version yet: Releases.
I suggest to leave the workaround for now and drop it when SYCL2020 will be officially supported in AdaptiveCPP.

"Officially supporting SYCL 2020" may be more complicated than it sounds but it's fair to keep this workaround until a release of AdaptiveCpp is able to compile oneMKL Interface. Thanks
