Re: VIM crash with YouCompleteMe plugin

Hm, I sent a reply to this but it never made it to the list. A newer
reply in the same thread made it. I've no idea what's going on, but I'm
going to try again.

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?

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.
