Arch Linux

Description:
I downloaded the source for VLC, then I had to install some deps to be able to compile it.
After restart, today I've deleted the package I made, cleaned the pacman cache and reinstalled
VLC from official repo.
Then I got segfault when trying to run vlc or the vlc-gen-cache.
I've checked with dmesg and the segfault was in libc 2.19.

Additional info:
deps installed:

[2014-04-17 02:34] [PACMAN] installed xosd (2.2.14-7)

Steps to reproduce:
Install VLC.
Install deps for building VLC.
vlc and vlc-gen-cache crash with segfault.
Remove deps and it works.
