Package: libc6
Version: 2.9-18
Severity: important
When installing libc6 from unstable on lenny multiple important programs
SEGFAULT. Among them are cups and update-menus.
To reproduce install libc6, libc6-dev, libc6-i386, libc6-dbg and locales
from sid on lenny and try running update-menus with any parameters.
To examine the problem further I rebuilt update-menus from source with
"-g -O0" and ran it in gdb with the following result:
(gdb) run
Starting program: /home/alve/menu/menu-2.1.41/update-menus/update-menus
Program received signal SIGSEGV, Segmentation fault.

When downgrading libc6 and locales to 2.7 and running the same binary again the
problem vanishes.
