I'm suspecting this is related to running Cygwin 1.7.

In looking back though some notes I started having bash shell problems
after upgrading from 1.5 to 1.7. 

Now on 1.7 if I try to run bash as a login shell it just gets "Bad
address" or segfault errors and immediately exits the shell which also
probably affects 'ssh'.

I don't remember having any bash problems when I was running Cygwin 1.5
on this machine.  My notes reflect screen copies showing bash able to
run as a login shell without any problem.


Regards,
Gerry
