After emerging sys-devel/prelink and configuring as per http://www.gentoo.org/doc/en/prelink-howto.xml segfaults occur in various applications. Reproducible: Always Steps to Reproduce: 1. Emerge sys-devel/prelink and configuring as per http://www.gentoo.org/doc/en/prelink-howto.xml 2. Reboot 3. Actual Results: New segfaults apear in /var/log/messages Expected Results: No segfaults apear in /var/log/messages nvidia-drivers should add to the prelink blacklist in /etc/env.d
Created attachment 314713 [details] Example blacklist file for prelink Example blacklist file for prelink that should be added to the nvidia-drivers ebuild

This is rather weird, since NVidia recommends prelinking their binaries: http://lists.freedesktop.org/archives/wayland-devel/2012-March/002798.html :-/ Before making a decision to block prelinking, it should be verified whether this bug is actually for real rather than some fluke on the OPs system.

Please describe the additional evidence you require.
I finally installed prelink and I'm unable to reproduce this.
I can't reproduce this either on two different systems.
You're going to have to follow the Gentoo backtrace guide, http://www.gentoo.org/proj/en/qa/backtraces.xml and try to get us a backtrace when you're using prelink.
