Hi Martin,
Thank you for the feedback.

You're right — I reviewed commit 9cc873e85800 and now understand that the test is designed to validate specific LLVM code generation, not just runtime behavior. I see how my change, although addressing the warning, could unintentionally alter the generated instructions and defeat the purpose of the test.

I'll drop this patch to preserve the original test intent. Thanks again for the context!

Best Regards,
Prabhav
