That might be dangerous, but I wouldn't call it incorrect. NetBSD is big
on backwards compatibility; if things are working correctly (and they
almost always are), there's no problem using new libraries with old

Andreas's build didn't really crash... installation of the new libc
caused the crash, and even if you build to a separate DESTDIR and
install from there, there's a window where your libraries and binaries
aren't matched. My question is why the old binaries are crashing with
the new libc... something's wrong if you have to recompile all your
binaries after upgrading from 1.5 to -current (especially since there
hasn't been an a.out to ELF switch on alpha).

Perhaps, but I wouldn't say that it's "incorrect" to do so.
