It's not even setting unused stuff. It's setting one location to a bogus value and then immediately overwriting it with the correct value. This process doesn't even have any side-effects. It probably doesn't even change the load locations of the shared libraries, though I haven't checked that. All it does is shift some of the dynamic linker code up by a few bytes. When we looked at this before, I think we decided the NIS code must be reading from a garbage address that happened to fall into the dynamic linker. That still seems the most likely explanation.
