You surely mean

  https://lists.gnu.org/archive/html/bug-bash/2022-07/msg00065.html

and especially

  https://lists.gnu.org/archive/html/bug-bash/2022-07/msg00073.html

(which quotes)

      The 0x (or 0X) prefix in base 16 is optional so only skip over the
      prefix if the character following it is a valid hex char.  The C99
      standard is clear that given the string "0xy" zero should be returned
      and endptr set to point to the "x"

though my "advise" is shows my bash geek status is much weaker
compared to what Greg Wooledge posted, referring to a much earlier
discussion that i was unaware of.

Sadly i keep

  jobs_selection ()
  {
      local j= a=${AWK:-awk};
      [ $# -gt 0 ] && j='&& $2 !~ /(^| )('$(echo "$@" | tr ' ' '|')')( |$)/';
      j=$(jobs -l | $a -F '[][]' '/^[[]/'"$j"'{print "%" $2}{next}');
      echo $j
  }

  $ alias j-
  alias j-='jobs_selection'

for "kill $(j-)" around.
