"Variable function parser inactive" -- interesting, did they apply the unofficial patch to namespace-prefix function definitions? This poster[0] seems to not have it, though. Who is right? The test at that github link seems a bit sketchy, by using a simple name like "a" instead of, say, __test_bashbug_a, and not checking the output very thoroughly. But it seems like it would fail the other way if there's a command named "a" in OS X's PATH...
