I started having trouble with vim crashing for me. I’m on OSX with homebrew and rbenv, and it crashed when editing Ruby files. I would get a segmentation fault.

After some googling which was not particularly fruitful, the solution I came up with was:

• switch to the system ruby rbenv shell system
• uninstall vim completely with homebrew brew uninstall vim
• reinstall vim from head brew install --HEAD --override-system-vi vim

This seems to have fixed the problem, though I do not know if it was switching to the system ruby or installing from head. This may require extra study which I do not have time to do now.
