Yep, lot of times. If I remember correctly, my glibc-2.2 -> glibc-2.3
was like that, and so were many glibc-2.3 upgrades.

Though recently I have started installing each package into a fakeroot
and then copy the files over to their final destination.

In the scenario you mentioned, though the vendor says glibc-2.3.4 it
is in reality glibc-2.3.4 + patches from glibc cvs + vendor specific
patches. So installing a prisitine glibc-2.3.4 is probably a downgrade
rather than an upgrade :)
