Package: libc-bin

Version: 2.13-0ubuntu13

Severity: Critical

Source: eglibc

Architecture: i386

System having installed with some 3rd party loaders (ld-<name>.so.x) in /lib 
directory. With these loaders present if we run ldconfig, its removing the 
system loader symbolic link ld-linux.so.2 in /lib directory from 
/lib/i286-linux-gnu/ld-2.13.so and creating the symbolic link to one of the 3rd 
party loaders(in my case link to ld-nails.so.2) present in /lib directory. As 
ldconfig not link to proper system loader, system gets unusable and system 
crashes if we reboot.

Captured the strace logs for "ldconfig".

This issue reproduce only on Ubuntu 11.04. As ldconfig is creating symbolic 
link causing the system unusable. Want to know why ldconfig is linking to 3rd 
party loaders instead of system loader ld-2.13.so and appreciate if you could 
provide the workaround for this issue.

We don't maintain Ubuntu; you'll want to get in touch with the Ubuntu
folks.

Sorry for the trouble,
Jonathan
