When running Xorg with x11-drivers/xf86-video-virtualbox-3.2.12 on a hardened system, it fails to load the module with the following error: [ 27963.699] dlopen: /usr/lib64/xorg/modules/drivers/vboxvideo_drv.so: undefined symbol: vgaHWGetHWRec When recompiling the driver with the vanilla gcc instead of the hardened one it loads fine.
