Hi,
I just spent some time hunting done a segfault that was cropping up recently
for me, and I have narrowed it down to some python threading that the
clang_complete plugin is doing. I have attached a minimal vimrc that is needed
to make the bug appear, the two stripped-down plugin files (just put them into
~/.vim/plugin), a gdb backtrace log and my version information (it's the newest
one with all patches applied).
The segfault happens in the vim.eval(getline()) call in libclang.py. The
comment above refers to a short sleep being necessary for vim to initialize
itself, and indeed it seems to be timing related: the bug only appears with
larger cpp files, and if I increase the sleep time the bug disappears. Here is
a pretty large cpp file to test it with:
https://hg.mozilla.org/mozilla-central/raw-file/4b24c5ab84cb/js/src/jstracer.cpp
Unfortunately I don't really know enough about the vim internals to fix it
myself, but maybe it's actually not as complicated as it looks.
Cheers,
Jan
