Since vim 7.3 patch 429 (on Ubuntu Precise/12.04), it looks like there's a
segfault issue when doing "cclose" on BufUnload in a python function. In
particular, it happens on 7.3 patch 547 (Ubuntu Quantal/12.10), and is also
happening on 7.3 patch 762 (latest tag in Mercurial checkout).
Here's how I'm able to reproduce it:
Create a file /tmp/blowup.vim:
pyfile /tmp/blowup.py
botright 3copen
autocmd BufUnload * python leaving_buffer()
Then create a file /tmp/blowup.py:
import vim
def leaving_buffer():
vim.command('cclose')
vim.command('quit')
Now run "vim -u tmp/blowup.vim /tmp/foo" (in my case, /tmp/foo does not exist).
Do ":q" in vim, and it will segfault:
Vim: Caught deadly signal SEGV
zsh: segmentation fault (core dumped) vim -u /tmp/blowup.vim /tmp/foo
I compiled it using the Ubuntu packaging for Precise, against the mercurial
checkout for 762. Here is the "--version" output:
guin:vim-quantal$ vim --version
