I don't think that's a normal effect.

You can try and debug it this way:


_debug_history() {
  _complete_debug _history_complete_word
}
debug_history .complete-word _debug_history
bindkey '^[/' _debug_history


Then when you use the command you should get a log of what it was doing,
though if you have to abort you may well find you have to look for the
most recently created file in /tmp to discover what that was.  If
you get anything, post the result.
