Hello,
I have tried to re-use the package calfw (https://melpa.org/#/calfw)
that I had not used in a while.
Sadly, it did not work and the backtrace looked rather strange. After a
while I have been comparing the bytecode of the faulty function that I
have with my present version of emacs :
GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.20, cairo
version 1.16.0)
to the one that was compiled with emacs 28.2 which was working when I
was using it.
Emacs 30.0.50 bytecode
(defalias 'cfw:dest-ol-selection-clear #[(dest) "\304!\305 :\203
@\306\n!\210 A\211\202*\307!\310\305\311 #)\207" [dest #1=#:--cl-var-- i
#2=#:v #[(cl-x) "\301!\204 \302\303\304D\"\210\305H\207" [cl-x #[(cl-x)
"\302! >\205 \303\207" [cl-x cl-struct-cfw:dest-tags type-of t] 2]
signal wrong-type-argument cfw:dest 10] 4] nil delete-overlay #[(cl-x)
"\301!\204 \302\303\304D\"\210\305H\207" [cl-x #[(cl-x) "\302! >\205
\303\207" [cl-x cl-struct-cfw:dest-tags type-of t] 2] signal
wrong-type-argument cfw:dest 10] 4] \(setf\
internal--with-suppressed-warnings\) ((lexical cl-x))] 5 (#$ . 69087)])
Emacs 28.2 bytecode
(defalias 'cfw:dest-ol-selection-clear #[(dest) "\305!
>\204 \306\307\310D\"\210\311H\312\n:\203(\n@\313 !\210\nA\211\202 *\305!
>\2048\306\307\310D\"\210\211\311\312I)\207" [dest cl-struct-cfw:dest-tags
#1=#:--cl-var-- i #2=#:v type-of signal wrong-type-argument cfw:dest 10 nil
delete-overlay] 5 (#$ . 60812)])
The error raised in the backtrace in emacs 30 is produced by the
function call :
\(setf\ internal--with-suppressed-warnings\) ((lexical cl-x))
It seems that the problem is actually coming from the byte compiler.
Maybe calfw is using a particular combination of features that stumbles
on this problem.
Best,
S.

Thanks, I'm therefore closing this bug.
