Using built-in terminal breaks lsp server

[Ashymad]

I work on C projects using the clang lsp, and used deoplete with this setup successfully before. While working on a C project if I open a split terminal window (:terminal) to execute some commands, after some time (a random amount, it can take a while or be quick, but it always happens) completion stops working and nvim spams with error messages:

It spams like this every minute or so after it happens for the first time.

My plugin configuration:

require('packer').startup(function(use)
    use 'wbthomason/packer.nvim'

    use { 'neovim/nvim-lspconfig',
        config = function()
            require'lspconfig'.clangd.setup{}
        end
    }

    use { 'Shougo/ddc-source-nvim-lsp',
        requires = {'Shougo/ddc.vim', 'neovim/nvim-lspconfig'}
    }

    use { 'Shougo/ddc.vim',
        requires = {
            'Shougo/ddc-ui-native',
            'vim-denops/denops.vim',
            'Shougo/ddc-source-nvim-lsp',
        },
        config = function()
            vim.fn['ddc#custom#patch_global']('ui', 'native')
            vim.fn['ddc#custom#patch_global']({
                sources = {'nvim-lsp'},
                sourceOptions = {
                    ["nvim-lsp"] = {
                        mark = 'L',
                        forceCompletionPattern = '\\.\\w*| =\\w*|->\\w*' },
                    }
                })
            vim.keymap.set('i', '<Tab>', function()
                local col = vim.fn.col('.') - 1
                if vim.fn.pumvisible() == 1 then
                    return "<C-n>"
                elseif col <= 1 or vim.fn.getline('.'):sub(col, col):match('%s') then
                    return "<TAB>"
                else
                    return vim.cmd("call ddc#map#manual_complete()")
                end
            end, {expr = true, silent = true})

            vim.fn["ddc#enable"]()
        end
    }

end)

Fixed. Please update ddc.vim.
