From: JC Petkovich <jcpetkovich <at> gmail.com> To: bug-gnu-emacs <at> gnu.org Subject: 24.1; cperl-mode with evil-mode causes hang on syntax-propertize Date: Tue, 17 Jul 2012 15:04:04 -0400[Message part 3 (text/plain, inline)]Emacs hangs on the creation of a newline with evil-ret when in a cperl buffer with some POD documentation after the __END__. This doesn't appear to be a bug in evil, but instead a bug in cperl or syntax-propertize, but I can't tell for sure. I can reproduce it with emacs -Q and the following configuration: ;; evil-error-reproduce.el: (defalias 'perl-mode 'cperl-mode) (add-to-list 'load-path "<path to evil>") (require 'evil) (evil-mode 1) ;; end evil-error-reproduce.el Once this config is evaluated, open a .pl file which has POD after __END__ like the following: # hangs.pl: print "hello world"; __END__ =head1 NAME # end hangs.pl and open a newline after the print statement with evil-ret (bound to RET when in insert mode by default). I haven't been able to get further than this in debugging this problem.

It seems to be a bug in cperl-mode, tho maybe it can only be triggered via syntax-propertize. In any case, I've installed the patch below into the emacs-24 branch, and that should fix it.
