Memory poisoning failure for allocations on a device #634
Description
Environment Information
- UMF version (hash commit or a tag): main
- compiler, libraries, and other related tools version(s): clang-15, possibly other compilers
Please provide a reproduction of the bug:
- Build Unified Runtime with L0 and ASan enabled
- Run fuzztest which allocates memory on a GPU device
How often bug is revealed:
always
(always, often, rare)
Actual behavior:

Expected behavior:
CHECK passes.
Details
We need a way to determine in Disjoint Pool whether the allocation is made on a host memory or a device memory. In cases of allocations made on a host memory, we can enable memory poison/unpoison.
