vim crash with latest vim8、YCM、python3.6.3(pyenv) on CentOS

[iFanze]

I've searched for the solution for a long time, most of them were caused by python installed by brew on macOS. None of them works for me.

I did following things:

• Reinstall CentOS 7.3 x64 on my VPS
• yum update
• Install python3 with :

export PYTHON_CONFIGURE_OPTS="--enable-shared"
pyenv install -v 3.6.3
pyenv global 3.6.3

• Install vim8 with :

git clone xxxx
./configure --enable-multibyte \
            --enable-python3interp=yes \
            --with-python3-config-dir=~/.pyenv/versions/3.6.3/lib/python3.6/config-3.6m-x86_64-linux-gnu \
            --enable-cscope
make
make install

• I'm sure +python3 exists in vim --version

• Install YCM with Vundle, then:

cd ~/.vim/bundle/YouCompleteMe
./install --clang-completer

All done with success.

• Run ldd third_party/ycmd/ycm_core.so, output is:

    /lib64/ld-linux-x86-64.so.2 (0x00007f99d00aa000)

libpython.so seems to be OK.

But, when I run vim, it will crash with message:

$ vim
Vim: Caught deadly signal ABRT
Vim: Finished.
[1]    31198 abort      vim
                           %                                                                                                                                                      $ ;2R0;95;0c

And it makes the following outputs of my operations mess, unless I reconnect it with ssh.

if I debug it with gdb vim, it shows:

^[[2;2R^[[>0;95;0cFatal Python error: PyThreadState_Get: no current thread

If I comment Plugin 'Valloric/YouCompleteMe' in .vimrc, vim works.

I tried with the same configuration in a VM and I get the crash. However, it also crashes when I start Vim without YCM and try to load the Python 3 interpreter:

$ vim -c "py3 pass"
Vim: Caught deadly signal ABRT
Vim: Finished.
Aborted (core dumped)

I fixed the crash by compiling Vim with the --enable-python3interp option set to dynamic and adding the Python library path to LD_LIBRARY_PATH:

$ ./configure --enable-multibyte --enable-python3interp=dynamic --with-python3-config-dir=~/.pyenv/versions/3.6.3/lib/python3.6/config-3.6m-x86_64-linux-gnu/ --enable-cscope
$ make
$ export LD_LIBRARY_PATH=~/.pyenv/versions/3.6.3/lib

[iFanze]

It works, thanks a lot! So vim --version need to be like +python3/dyn insead of +python3, I think.

[micbou]

Seems so.

Same issue here on Gentoo after latest update. I manage to compile vim with +python3/dyn but it doesn't resolve problem

@0k00l dont reply with no new diagnostics to a closed issue. If you have a problem and believe that it is a YCM bug (fwiw, this issue is not, it’s an installation of vim/python issue), then raise a new issue and complete the issue template.

[bstaletic]

Just a blind guess, based on my recent interaction with a gentoo user.

vim --noplugins
:py3 pass

I expect this to segfault for you and if it does, it's not a YCM issue.

Got segfault - so it is not YCM issue

bash:

vim --version |grep python

echo:

+comments          +libcall           -python            +visual
+conceal           +linebreak         -python3           +visualextra

am I have to re-make Vim? Thank you for your help.

[bstaletic]

Usually the distros package python-enabled vim too.
