Have you tried using bash for your initial shell instead of zsh?  Under
this scenario, does gvim still crash?

Hmm...that sounds suspiciously line-termination related.

Switch shells to bash and see if the gvim failure still occurs.  If not,
then it's likely zsh internals related.
As with most problems, please collect the information as per:
