Last time I built BIND on an unfamiliar platform (AIX if you must know),
I had some failing tests as you describe. Turns out, named was actually
*dying* during the tests and that's why some of the tests were failing.
The test harness/subsystem wasn't very clear on the whole
death-of-its-major-component thing. I ended up having to use a later
version of gcc in order for named to not crash and for the tests to pass.
So, yeah, this might be very serious. named dying in production might be
rather inconvenient. You might want to dig deeper into why those
particular tests are failing.
