Got it. I understand it is frustrating to fix an additional bug during 
development. Also it is generally not good to revert a valid test case.

Are you in a hurry to land this recently? (e.g., land this for clang17) If not, 
I suggest to wait for me to fix the underlying issue after clang17 gets 
released. And if I take too long to fix it (e.g, 9.30), given the speciality of 
the patch, I think we can revert that test case and land this one that time. 
How do you feel about the idea?
