Is there any pattern to the errors? Are they ever before the zstty0
gets attached? If the latter, this isn't it. :-(

In debugging, I ran into address error traps at odd times just
after zstty0 was initialized. I saw this about 50% of the time.

If you see these crashes at other times, like before zsc0 gets attached
or well after zstty01 gets attached, then you have a different problem.

I'm sending the patch in a seperate EMail. Please try it.

Thanks!

Take care,

Bill
