glibc crash when launching certain applications

[Mathieu Leduc-Hamel]

I just update my system and when I launch certain applications it crash instantly. I didn't have time to install gdb and then right now my system is completly useless cause I cannot fix it by installing any update.

By example when trying to launch apt-get:
$ sudo apt-get install gdb
