Can you reproduce this issue using neovim nightly?

If yes, since you can't reproduce this issue with a default config, could you comment bits of your config until you find what setting is making neovim crash?

[1kit]

Can you reproduce this issue using neovim nightly?
Sure, I can give it a try

I already tried commenting out parts of my config and this is what I found.

I use Plug to install various plugins. When I have a count of 11 "Plug ..." calls in my init.vim, things are fine. The moment, I exceed 11, it crashes when I insert from clipboard. I have tried various combinations of the plugins. So it is not any specific plugin. It is just the number.
My .vimrc source my init.vim and I have the exact same dot files for vim8 and nvim. Vim8 works just fine for me.

[1kit]

So I built the master and tried the nvim from there. The same problem persists.
The version I see is "NVIM v0.5.0-477-gf9055c585"

thanks

@1kit if you can still reproduce this crash on master/nightly, please give us a way to reproduce it. You did not give us the content of your rc file :)

will reopen if someone can post a repro with 0.6
