Bug#489593: libc6: ldconfig segmentation fault

[GREY <greymail@poczta.fm>]

Package: libc6
Version: 2.7-10
Severity: critical
Justification: breaks the whole system

I have segmentation faults with ldconfig:

# ldconfig
Segmentation fault

And from /var/log/syslog:

kernel: ldconfig[2996]: segfault at d5bc6b76 ip 0806084b sp bfc097dc error 5 in ldconfig[8048000+96000]

I tried reinstall libc6 but without good results:

# dpkg -i libc6_2.7-10_i386.deb
(Reading database ... 225572 files and directories currently installed.)
Preparing to replace libc6 2.7-10 (using libc6_2.7-10_i386.deb) ...

dpkg: error processing libc6 (--install):

Processing triggers for man-db ...
Errors were encountered while processing:
 libc6

And from /var/log/syslog:

init: Trying to re-exec init
kernel: ldconfig[3178]: segfault at d5ad5b76 ip 0806084b sp bf81836c error 5 in ldconfig[8048000+96000]

This is very critical bug because without ldconfig I can't install/update any other software.
