Problem Description
Incorrect results occur when loading and executing OpenCL kernels compiled with clang-ocl with hip api on ROCm 6.1 in Ubuntu 22.04.
Operating System
Ubuntu 22.04.3 LTS (Jammy Jellyfish)
CPU
AMD EPYC 7413
GPU
AMD Instinct MI250X
ROCm Version
ROCm 6.1.0
ROCm Component
clang-ocl
Steps to Reproduce
Initially, compile the OpenCL kernel with clang-ocl.
Then, utilize HIP APIs like hipModuleLoad(), hipModuleGetFunction(), and hipExtModuleLaunchKernel() to load and execute the compiled binary within the host code.
Ultimately, incorrect results should be encountered.
Attached below is the source code and Makefile used for reproduction.
The first value is found to be incorrect upon running the attached source code.

@hyunjik-song Internal ticket has been created to investigate this issue. Thanks!
clang-ocl has been removed from ROCm, so this will not be addressed, but thanks for pointing this out!
