net-news/bnr2 (any version) simply says "segmentation fault" when I try to run it after upgrading to x11-base/xorg-x11-6.8.0-r4 but a downgrade back to x11-base/xorg-x11-6.8.0-r3 solves the problem. Reproducible: Always Steps to Reproduce: 1. emerge bnr2 2. emerge =x11-base/xorg-x11-6.8.0-r4 3. bnr2 Actual Results: segmentation fault Expected Results: program should run! I have switched back to x11-base/xorg-x11-6.8.0-r3 but everything else (kernel, etc) should be the same still.

I just upgraded my system to x11-base/xorg-x11-6.8.0-r4 and net-news/bnr2 still works for me. If you have any information that can be useful to track down this bug, please post. I'll try on some of my other machines and see if I can reproduce it there.
I emerged x11-base/xorg-x11-6.8.1.901 today to see if it fixes it, but it breaks bnr2 as well. It doesn't say "Segmentation Fault". Now it simply says "Killed". I know that's not much to go on... I really have no idea where to even begin looking for the cause of this. Everything else seems to work fine. I've tried the newest BNR2 0.14.6 and still have the same failed result.
I will add that I have tried to run it as different users and using different window managers and this does not affect the outcome. I have tried removing BNR2's data files and starting fresh with no success.
It may be Kernel related. I just realised, when I'm using 2.6.10 it says "Killed" immediately, regardless of xorg version. When I'm using 2.6.9, it runs on xorg 6.8.0-r3 but gives the "segmentation fault" on newer versions. Perhaps it's two independant problems. Sorry for the confusion.
Thanks, after upgrading to 2.6.10 I'm able to reproduce this. Currently trying to find the cause of it.
It's killed directly after calling execve() so probably a kernel change or bug that's incompatible with the kylix generated code. sven@luna ~ $ strace /opt/bnr2/bin/BNR2 execve("/opt/bnr2/bin/BNR2", ["/opt/bnr2/bin/BNR2"], [/* 61 vars */]) = 0 +++ killed by SIGKILL +++
I got a simple kylix program (a "hello, world" type of program) and it fails in exactly the same ways under the two different setups. So it appears it's not a BNR2 specific problem, but perhaps a kylix or libborqt (or Xorg or kernel) problem. Should I close this and/or file a new bug? strace shows more progress under RNEL 2.6.9 (before the "Segmentation fault") but it still appears like it's not making it very far.
I figured it out! It was nxserver's libXrender.so.1 breaking, it was being used rather than standard version. I took out /usr/NX/lib from ld.conf and now things are working properly in kernel 2.6.9 with any xorg version. I am changing this bug to INVALID since it was not bnr2 problem at all. I will file a new bug for kylix apps broken in kernel 2.6.10 after testing with a couple more test apps.
