Thanks for reporting.

I met below failure when following the steps of provided reproducer.
Could anyone help check what's wrong with that?

Sorry this seems to be a bug in the reproducer. Could you please change
the compiler parameter to "COMPILER=clang-16" and rerun the command? We
will fix the issue ASAP.

Any update for the reproducer? I would like to post v2 with the fix. I
doubt it's the same issue as another report on this patch, while not
quite sure.

Setting "COMPILER=clang-16" is exactly the correct fix and should
reproduce the issue in this report. We've fixed the steps of reproducer
but this will only take effect in future reports.

Thanks, Yujie. I thought you were asking me to use "COMPILER=clang-16"
to get information to debug. I have done the testing according to
Nathan's suggestion and can confirm it's the same issue as the one on
arm64. Will post v2.
