I coudn't see this on file anywhere, so I filed:

  http://bugzilla.mozilla.org/show_bug.cgi?id=208496
  "Incorrect scope when |with (f)| is used inside the definition of 
|function f()|"

I have cc'ed Itaj, and added his testcase to the JS testsuite:

  mozilla/js/tests/js1_5/Scope/regress-208496.js
