"free(): invalid pointer" when doing async searches with neovim

[GabeDuarteM]

Issue description

Its not always, but I noticed that when you try doing a search that will result in a lot of entries, it first displays a weird error (its gigantic, so I will paste it below), and then it starts the async search, and whenever I switch to the search buffer, my normal buffer gets replaced with the same contents as the search buffer (minus highlighting, image showing this below), and whenever I try to close any of the buffers (by doing :bd or :q), neovim crashes and the following message appears on the console:

the neovim crash

free(): invalid pointer                                                                                                                                
                       zsh: abort (core dumped)  nvim
                                                     %

the buffer being replaced with a copy of the search buffer (it updates whenever the search buffer updates as well):

the gigantic first error:

Things about your system and environment

field	value
os	OS X Monterey 12.2.1
vim	NVIM v0.7.0
backend	ripgrep 13.0.0
locale	en_US.UTF-8

• log:

Its difficult to post the log, as there's a lot of private code as well in there... If there's anything in specific, I can try to search for it

• vimrc:

let g:ctrlsf_ackprg = 'rg'

let g:ctrlsf_auto_focus = {
    \ "at": "done",
    \ "duration_less_than": 1000
    \ }

let g:ctrlsf_mapping = {
    \ "next": "n",
    \ "prev": "N",
    \ "quit": "gq",
    \ }

let g:ctrlsf_extra_backend_args = {
    \ 'rg': '--hidden --glob "!.git/*"'
    \ }
let g:ctrlsf_populate_qflist = 1

nnoremap <leader>f :CtrlSF<space>
nnoremap <leader><leader>f :CtrlSF<space><C-R><C-W>
vmap <leader><leader>f <Plug>CtrlSFVwordPath
command! CSFT execute ":CtrlSFToggle"

• file:

Theres nothing in specific on any file, its random, I can make the same search twice, and first it breaks, and then it works fine... I noticed it usually happen on async searches, with lots of results being displayed

[dyng]

The error messages implies it's more likely a problem related to nvim. Sorry for that I'm not using nvim so I can't figure out the root cause, but updating your nvim to latest or downgrading to a specific stable version may help.

[HTcbaldwin]

Had the same issue, turns out I was using an older version of Neovim. For whatever reason, the package in Ubuntu hasn't been updated in some time.

Pull and build from source, or try the AppImage, and give that a shot!
