Please try to open the attached file in emacs -Q, and after moving point
to the beginning of the 3rd line, type 'M-q'. When debug-on-error is t,
it fails with such backtrace:
Debugger entered--Lisp error: (error "Invalid search bound (wrong side of point)")
re-search-backward("[ \11]\\|\\c|.\\|.\\c|" 280 0)
fill-move-to-break-point(280)
fill-region-as-paragraph(184 210 nil nil 186)
fill-comment-paragraph(nil)
fill-paragraph(nil t)
funcall-interactively(fill-paragraph nil t)
command-execute(fill-paragraph)
BTW, evaluating debug-on-error in *scratch* shows t by default,
but 'C-h v debug-on-error' shows it's nil actually, strange.

I can reproduce this bug, too.

With `C-x C-e'? Then this happens:
---
If ‘eval-expression-debug-on-error’ is non-nil, which is the default,
this command arranges for all errors to enter the debugger.
---

Yep.

This is fine, just a little strange.

This doesn't happen now in Emacs 29. Instead I get:
abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc ; def
; def
; def
; def
; def
; ghi
Is that the result we're supposed to get, though? I'm not at all sure
how fill-paragraph/comment-start are supposed to interact here.

This is what it always did in all earlier versions until the recent
breakage that is fixed now.
