Updated my bash on CentOS 6.5 this morning so your test fails:

bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x'
this is a test

There's a second vulnerability that escapes the first bug patch.

 env X="() { (a)=>\\" bash -c '/dev/stdout date'

If this prints the date, you still have a hole where bash can write content
to arbitrary files. ( And this trick somehow makes it write the date to
/dev/stdout.  )

New patch released overnight which seems to fix that.
