Driver 616.64: Some OptiX-IR kernel crashes in Debug

Hello,

Recently, I have updated the driver to 616.64 and noticed a program in my OptiX wrapper library crashes in Debug build.

As always :), I suspected OptiX-IR and gave ptx try instead, then the crash disappeared.

I extracted the program in the wrapper library as a reproducer.
It uses a .ptx by default and does not crash.
You can use .ptx by setting MATERIAL_SETS_USE_OPTIX_IR to 1 then will see a crash at a kernel launch.
