Just as a reminder, this is on FreeBSD, in case it might make any
difference.

I have tracked down where it is hanging, but I don't know enough zsh
internals to know why.

When processing the %prep section of the Y tests,
it calls
    comptestinit -z $ZTST_testdir/../Src/zsh
which calls comptesteval() in Test/comptest.

On line 83 in comptesteval() it calls
    zpty -r -m zsh log_eval "*<PROMPT>*"
and thats where it hangs.  zpty never returns.

I hope this helps.  Let me know if there is anything more I can do to help
troubleshoot it.
