Connect.  That's all.  My crash happens in less than 3000 bytes
of transferred data, always.

If you want, I can send you my entire environment but before I
do that I'll update CVS.  Maybe it was a bad day when I downloaded?

Yes, it's all I've got currently.

I had a SIMILAR bug a LONG time back with an XScale but it would take
a long long time for it to crash and that very well could have been
application code.
