Or an earlier version of bash (4.1), which I'm assuming (haven't installed any patches within the last month on a centOS6 machine) hasn't got the issue?
If you see that "ignoring function definition attempt" message you definitely have the first patch applied (but not necessarily a fix for the second problem) That diagnositc was added by the patch itself. See http://ftp.gnu.org/pub/gnu/bash/bash-4.1-patches/bash41-012
Maybe you have auto-update turned on and didn't realize it?
