deoplete causes the segv error when vim is exit #1114

Closed zhuzhzh closed 4 years ago

zhuzhzh commented 4 years ago

Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

Problems summary

when vim exits, segv signal is catught. And ls output will be messy

Thru the multiple experiments, I confirmed the issue is caused by deoplete. And it's not due to the conflicts with other plugins.

Please test the latest version of Vim. Because the latest Vim includes Python interface changes.

I have tested it, but I don't reproduce the problem.

How to reproduce the problem from neovim/Vim startup (Required!)

vim
:q

This instruction is correct? Why other people does not complain about the problem??

Shougo commented 4 years ago

And it seems Vim's problem. Both deoplete and nvim-yarp cannot crash Vim.

You should report the problem in Vim issue. And you can bisect Vim's commit.

Shougo commented 4 years ago

And please test it in other environment. It should be reproduce-able in every environment.

zhuzhzh commented 4 years ago

@Shougo I am doing the experiments. baiscally, I unintall all the packages I installed. Then install them one by one. After installing libffi, openssl, python3.8.3, vim8.2.1149, vim doesn't crash. so it should be the conflict issue of vim and other library. deoplete by happen uses this library. I will close this issue.

Thanks!

Shougo commented 4 years ago

OK.
