NeoVim crashing on auto complete

[Augusto César Dias]

I'm having crashes when I choose one of the autocomplete options.

As soon as it fills the parenthesis, neovim crashes.

I went disabling all plugins to see if it were any of them conflicting until I left only coc. Then I removed all my settings to be sure it wasn't any of them.

My vim.init ended up like this:

set shell=/bin/zsh
let mapleader = "\<Space>"

" =============================================================================
" # PLUGINS
" =============================================================================
" Load vundle
set nocompatible
filetype off
call plug#begin(expand('~/.config/nvim/plugged'))

Plug 'neoclide/coc.nvim', {'branch': 'release'}

call plug#end()

My NeoVim info:

With NVIM 0.4.4 it works fine
