Subject: [PATCH] cperl-mode: don't freeze over a cool regexp
Date: Wed, 2 Sep 2020 22:06:40 +0200

[Message part 1 (text/plain, inline)]
That bug exists since 14 years, but only surfaces if the regexp has a
closing brace in the wrong place (two characters before an unfinished
group starts).  The reason is that `cperl-forward-group-in-re' failed
to report unbalanced parentheses: In the function, the error was too
narrowly localized and gets lost before returning.

Patch attached, including two test cases.
