Segfault in vim and lua -- set_ref_in_item
This is a vim bug: https://github.com/vim/vim/issues/434
I am experiencing what is probably a niche error, but it's a bit frustrating nonetheless.
Prerequisites: Vim with color_coded, tmux
Steps to reproduce: 1. Open Vim on a file that causes color_coded to be loaded 2. Immediately open a new tmux pane or window 3. Vim segfaults.
Here is my gdb output:
#0 0x0000000000463241 in set_ref_in_item () #1 0x00000000005d4e09 in ?? () #2 0x00007ffff5397950 in ?? () from /usr/lib/liblua.so.5.3 #3 0x00007ffff5397d0b in ??

This error doesn't (usually) occur if color_coded is given a few seconds to initialize. I think I've encountered it once or twice even with a fully loaded file, but I haven't been able to reliably reproduce it.
This is not a huge hassle if I remember just to wait a short while after opening vim, but it can be annoying and is probably preventable.
