it seems that libc-2.1.90 (and associated libraries) in the May 19 release
groff dumps core, man stopped working, lpr ditto, LPRng does not allow
remote printing, etc.
After I downgraded to the old libc-2.1.3 (from 6.2, or Mandrake), I also
had to downgrade to gcc-2.95.2 in order to be able to do any compilations.
Other components were broken too: Gnome-Terminal exited demanding a version
og libc6.so with version 2.2 (or something like that).
I had to go to the Mandrake-cooker distribution for gcc-2.95.2, to the
helix distribution for working gnome-core, etc.
There should be a warning in your distribution about what does not work!
Some of the bugs have been reported before: 11464 11576, 11566, but the
culprit (libc-2.1.90) was not identified.
Actually, refering to bug #11928 I found this out too. It was glibc 2.1.90
from May 19th.
If you upgrade to Glib 2.1.90 of May May22 that glbc-2.1.89-13 RPMS,
everything should work just fine, the gnome-terminal, man, and lpr etc
