The 2.2 version of glibc is _not_ fully compatible with the 2.1 version.

When I upgraded glibc on my RedHat 6.2 system up to 2.2.4 along with 
many other rpms from RedHat 7.2, several of my gnome applications quit 
working.  Nautilus and gnumeric and Ximian's RedCarpet program would run 
and then segfault.

However, most other programs continued to work fine.
