Re: VIM crash with YouCompleteMe plugin

I tried to compile python-3.8.2 myself and it seems to take me ahead with the previous issue.  I don't see any vim crash anymore. Thanks a lot for your help!

However, the YouCompleteMe plugin still doesn't work. When I open vim, it shows an error at the bottom:
YouCompleteMe unavailable: /remote/cwh3/common/installations/local/lib/python3.8/lib-dynload/_socket.cpython-38-x86_64-linux-gnu.so: undefined symbol: PyFloat_Type

Thanks for your response and others too.

The gdb trace indicates the crash is happening during Python
interpreter initialization.  Can you rule you YCM by trying

   vim --clean +'py3 print("hi")'

and seeing if it crashes?

 

This also crashed.

Another thing you could try is export PYTHONFAULTHANDLER=1 before
running vim, then Python will print the Python-level traceback on SIGABRT.
It might or might not help figure out what's going on.

This didn't help. There wasn't any output at all. 

In my setup, I bulit vim myself, but not python. Perhaps, it is worth trying to build python also once. I will try that and see. As I understand, the option '--with-valgrind' is only useful to avoid certain warnings with valgrind, but doesn't really make my difference to what I am trying. Anyways, since I would be building python, I would still provide it.
