The upgrade from Marvericks to Yosemite went smoothly except for one thing: vim is segfaulting every time I use Commant-T

The most common answer is that vim has been compiled with a different ruby version than Command-T. However, after being sure to recompile Command-T the problem was still there.

Turns out that I had Command-T on the vim’s plugin directory. After removing it and cloning it into ~.vim/bundle, and recompiling it with:

ruby extconf.rb
make

it started working again. Be sure to leave no Commant-T files on the plugin folder. I left commant-t.vim by mistake and even though I was no longer getting SEGFAULTs, command-t was not working properly.
