Perhaps this is a bug for older clang releases (the bot > tested with clang-14). Thanks for this info. We re-tested with various versions of clang. clang-14 throws this error, while clang-15/16/17 have no problem in this case. We will consider adjusting our compiler coverage and remove the old clang-14.
