RE: post-self-insert-hook being reset?

[Phillip Lord <phillip.lord@newcastle.ac.uk>]

There are a class of hooks (post-command-hook, after-change-functions) that nil themselves on error.

This normally happens at the C layer, and is there to prevent Emacs from getting hung. I guess post-self-insert-hook 
is one of these.

It's a PITA to debug from lisp I am afraid.

Subject: post-self-insert-hook being reset?

Hi all,

I am using smartparens and it adds a really useful post-self-insert-hook called sp--post-self-insert-hook-handler.

However, after a while of just general editing, the hook disappears!

I've grepped my entire config, all my packages from MELPA etc, to see if anything is resetting the post-self-insert-hook list, but everything looks well behaved.

Is there any standard emacs package, or error handling, that would remove a hook for some reason?

FYI, my .emacs https://github.com/fommil/dotfiles/blob/master/.emacs.d/init.el

Best regards,
Sam
