I have the following:

----
source ~/.zdomain
----

which just has "domain=local.prunille".

----
if [[ -n $SSH_AUTH_SOCK ]] then
  if [[ `whence -w _call_sshagent` == '_call_sshagent: function' ]] then
    _call_sshagent -r
  elif [[ -n $SSH_AGENT_PID ]] then
    eval `ssh-agent -k`
  fi
fi
----

Here "_call_sshagent -r" was executed. I've attached the source of
this function.

  kill -HUP $PPID 2>/dev/null

The OS isn't linux, so nothing should be done here.

So, it seems that zsh froze in _call_sshagent.

Well, problems started to occur before I tried to exit zsh. There
could have been a problem in .zlogout due to an earlier memory
corruption or something like that.

If this is memory corruption, then this could be the same bug I've
been noticing for years...
