Here's the relevant test:
testfunc='() { echo bad; }' bash -c testfunc

This is a MUCH better test for most people.  Hanno's test script is great for detail, but most people don't need the 
detail.

I'm putting that email in my timeline at http://www.dwheeler.com/essays/shellshock.html#timeline - this is an EASY test 
people can directly use.
