Subject: bug#34373: 26.1; Missing range check in rx-submatch-n
Date: Thu, 7 Feb 2019 19:01:33 +0100 [thread overview]
Message-ID: <C266781B-8A07-423F-8DC6-7FA166D681E8@acm.org> (raw)
`rx' should protect its own abstractions and never generate an invalid regexp, but will if given a bad submatch number:
(rx (group-n 0 "x"))
=> "\\(?0:x\\)"
It's a missing range check in rx-submatch-n.
