I try to use apt-get, apt-cache or anything which use libapt.
I debugged it, and I saw this:
(gdb) run dump

The error occurs evertyme I run apt-*, so I'm sure that there is a
problem in my libapt.

Well, msync is not supposed to fail. Your system is broken. Are you using
some weird filesystem/linux version?
