Characters get deleted as you type in vim files after saving

[gcmt]

Hi, I noticed a strange behavior while editing vim files with MacVim and with Vim that comes shipped with MacVim itself. After saving a vim file, whatever word I type gets deleted after the first character so writing becomes practically impossible.

I'm running MacVim 7.3 (snapshot 66) on Mac OS X Mountain Lion 10.8

Can't repro this so it's highly likely that this is an interaction with some of your maps/plugins. Make sure you don't have something mapped to <C-p>, <C-x> or <C-u> (in insert mode).

If that doesn't help, try (temporarily) removing all of your plugins except YCM and see if it persists. If the issue goes away, then some other plugin is causing you issues.
