 > A workaround would be to add `-Wno-error=unused-but-set-variable` with
 clang 13 or later. The better solution would be to fix the code for

 consultation has already occurred. Here is their bug report:

 Thanks for the background detail, as well as a link to the patch.
 (Googling this was on my to-do list, but the sudden behavior change made
 me second-guess my sanity!)
