The patches are available at ftp://ftp.cwru.edu/pub/bash/bash-3.0-patches.

It's already on the web page:  
http://cnswww.cns.cwru.edu/~chet/bash/bashtop.html,
and that is in the FAQ.

I will add it to the distribution information in the FAQ, though.

It solves the problem when I test the fully-patched bash.  Please apply the
patches and test again.
