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.

Before I dive further into this, can you first check whether the bug-fix
for bug#11739 (see patch below) happens to fix your problem as well?

I'm afraid the patch does not appear to do anything. Same symptoms.
Same procedure was used to reproduce, using a patched cperl-mode.el instead
(I made sure it was not loading the old elc, I moved it elsewhere).

Indeed, I could reproduce it without evil. 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. Thanks you,
Stefan
