bug#75067: 29.3; randomly unresponsive while typing

[Devon Sean McCullough]

Merry Solstice!

I would like to know what happened
which led to an unresponsive emacs
burning 100% CPU, fans roaring.

By the time I tried view-lossage it was too late.
My only clue is is #<bytecode 0x1c58a1a1743c49cf>

                Peace
                        --Devon

P.S.  No hits from
(let ((h #x1c58a1a1743c49cf)
      (count 0))
  (mapatoms
   (lambda (s)
     (incf count)
     (let* ((f (symbol-function s))
            (b (and (byte-code-function-p f)
                    (aref f 1))))
       (when (or (= h (sxhash s))
                 (= h (sxhash f))
                 (= h (sxhash b)))
         (message "Atom %S Function %S ByteCode %s" s f b)))))
  count) ; => 81700
;; Perhaps someone can suggest a better way?

P.P.S.  It eventually stopped:
Debugger entered--Lisp error: (invalid-regexp "Regular expression too 
big")
