Then you can try

:verbose set cpo?

it will tell you where the option was last set.

Note that

let s:cpo_save = &cpo
set cpo&vim
"
" do some processing
"
let &cpo = s:cpo_save

is normal save-work-restore procedure, yet it will make :verbose point
to the latest script that did it. The danger is if the script gets
interrupted in the middle and forgets to restore.

Maybe even better would be for a script to do

try
let s:cpo_save = &cpo
set cpo&vim
"
" etcetera
"
" possibly
catch /^Vim\%((\a\+)\)\=:E1234/
"
" handle error 1234
"
finally
let &cpo = s:cpo_save
endtry

but I doubt that there are many scripts that careful.

see
:help :try
:help :catch
:help :finally


Best regards,
Tony.
