Further testing: I backed out to the xserver-xorg-video-ati in the archive, and the problem remained unreproducible. I backed out to the xserver-xorg-core in the archive, and the problem became easily reproducible again. So I think it should be sufficient to build only xorg-server with -fno-stack- protector. I'm uploading that change now, and Matthias has added this bug to the list of known SSP issues for further investigation:
