From: Vincent Lefevre <vincent <at> vinc17.net> To: 33114 <at> debbugs.gnu.org Subject: bug#33114: 25.2; Emacs hangs on closing a perenthesis in a regexp in cperl mode Date: Mon, 22 Oct 2018 02:37:49 +0200
Consider the following file: # -*- mode: cperl -*- s/./(/e; 1. Open it with "emacs -Q". 2. Put the cursor just after the opening parenthesis. 3. Type ')' (closing parenthesis). This makes Emacs hang. A C-g alone has no effect. Several C-g in a row may give the control back to the user. Tested under Debian/unstable.
