Bug#778821: vim: SEGV in lua plugin

Package: vim
Version: 2:7.4.488-4
Severity: normal
Dear Maintainer,
* What led up to the situation?
Run Vim (both console and gvim) and after some time got a crash:
Vim: Caught deadly signal SEGV
Vim: Finished.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I don't have an exact testcase, it seems to happen after vim was left idle
for some time and I start typing again.
Yesterday Vim crashed again after several months, so I enabled core dumps and today it crashed again.
* What was the outcome of this action?
[ The coredump below was for gvim but yesterday plain vim crashed too, so it looks like a
bug in core vim, not the GUI part hence reporting it on the vim package ]
Core was generated by `gvim'.
Program terminated with signal SIGSEGV, Segmentation fault.

I have several vim plugins, but only one uses lua AFAICT (rgrep 'lua ' ~/.vim/bundle): https://github.com/Shougo/neocomplete.vim
I have installed that plugin since October 2014 (I was using neocomplcache before, which doesn't use lua).
In my vimrc I have these neocomplete settings:
let g:neocomplete#enable_at_startup = 1
if !exists('g:neocomplete#force_omni_input_patterns')
let g:neocomplete#force_omni_input_patterns = {}
endif
let g:neocomplete#force_omni_input_patterns.ocaml = '[^. *\t]\.\w*\|\h\w*|#'
My full .vimrc and .vim directory is available at https://gist.github.com/edwintorok/d74a3dd0aa71a840b7d2
Here is the full backtrace as well:
