Nobody has claimed this yet.

## Diff
Things start to diverge around the last two hex numbers in the buffer

Start by running Feature/HLSLLib/asuint.64.test on the NVIDIA GeForce GTX 1070 configuration and compare the expected and actual buffer values shown in the report. Inspect the test and its execution path to determine why the final values diverge, then verify the failure is resolved without regressing the test elsewhere.
