Vim crashed with plugin using lua

[guotsuan]

Hi,

Vim crashed randomly but often if I enable the vim plugin using lua (neocomplete).

The gdb give the information:

Program received signal SIGSEGV, Segmentation fault.

Thank you very much. Let me know if you need more information.

I ran into the same problem here. Using plugins that have Lua components will make Vim segfault randomly (I really couldn't find the exact condition where Vim would crash).

It seems to me this is very similar to Debian Bug 778821. According to the bug status, it was fixed by Path 609 (2459a5e).

I'm also using Vim from Archlinux, which definitely includes Patch 609 (at the time I'm writing this, it's 7.4.884).

color_coded is one example plugin that will trigger this issue. There's a bug report related to this: jeaye/color_coded#68

Fixed by 7.4.954?

The fix seems very promising and reasonable to me, but I can't say for sure
it fixes the issue. Anyway, I'm pretty sure #468 is a duplicate of this
issue.

I have an environment that triggers this segfault frequently (but still
more or less randomly). I'll test the patch for some time and see
