Segmentation fault

Hi

I hope someone can help me.

Updated glibc from glibc-2.3.2-11.9 to glibc-2.3.4-2.10 (gblic-commont too)
on Redhat9.0.
After updated I saw some problems so that I reinstalled previous version.
Bad thing I could not
uninstall updated glibc so there are duplicated glibcs. I can't remove them.
Because I can't use
rpm and some other shell commands (vi, date, and more). If I use rpm
command, it ends with
" Segmentation fault ". Other commands give me same error message.

Pls help me..

Scott
