[Message part 1 (text/plain, inline)]

Hey Eli,

Thank you for pointing this out to emacs -Q. This problem is definitely related somehow to my own setup. I am not able to reproduce the problem on emacs -Q. Will try to figure out which part of my configuration is causing it. Thank you again!


  *   Andrey

I cannot reproduce this, neither with Emacs 28.2 nor with the current
emacs-29 branch.  Can you post a more detailed recipe, starting from
"emacs -Q"?

What I did:

  . copied the snippet you posted to a foo.el file
  . visited foo.el from 'emacs -Q"
  . typed "M-x check-parens RET"

This completed without any error messages.
