Re: Segfaults as non-root user
Hi, I also see the same problems that have been reported in the "Segfaults as non-root user" thread in September (http://lists.debian.org/debian-amd64/2005/09/msg00508.html). For instance with dpkg-parsechangelog, it crashes with dpkg-parsechangelog: failure: tail of debian/changelog died from signal 11 in /var/log/messages I find: Oct 19 14:55:01 ithif59 kernel: dpkg-parsechang[6180]: segfault at 00f0 rip 002a9623ae3b rsp 007fb1c0 error 4 As super-user, dpkg-parsechangelog runs fine. I am running a self-compiled 2.6.8 kernel on Tyan Thunder K8S Pro board with two opteron processors. I followed the pointers in the reply from Jochen Sprickerhof. However, I could not extract any useful information. Further, the segfaults that I see are reproducable. Are there any suggestions or workarounds?

Segfaults as non-root user
I recently installed the amd64 port onto an intel EM64t SMP machine. I am running the 2.6.12.6 kernel. The same issue occurs using the debian-packaged 2.6.11-em64t-p4-smp kernel. I cannot test on the 2.6.13 kernel due to a driver issue in the raid controler. The system was installed using a slightly modified unstable cd image and then packages from the testing branch were installed. The raid board on the machine is not supported until the 2.6.11 kernel and I was having difficulty getting a kernel satisfying that onto a testing installation cd. So far, I have found a few programs that segfault, particularly zsh and dpkg-buildpkg when run as a non-root user. They behave normally when run as root. In zsh the problem appears as: ~ % cd /tmp/test /tmp/test % ls -la /tmp/test total 12 drwx--x--x 3 john john 4096 2005-09-20 09:55 . drwxrwxrwt 7 root root 4096 2005-09-20 09:54 .. drwx-x 3 john john 4096 2005-09-20 09:55 pkgs /tmp/test % /tmp/test % cd pkgs /tmp/test/pkgs % ls zsh: 4707 segmentation fault ls /tmp/test/pkgs % And any attempts to execute commands elsewhere results in a segmentation fault. However, if the full path is used, the segfault does not occur: ~ % cd /tmp/test/pkgs /tmp/test/pkgs % ls -la total 6516 drwx-x 3 john john4096 2005-09-20 09:55 . drwx--x--x 3 john john4096 2005-09-20 09:55 .. drwx--x--x 18 john john4096 2005-09-20 09:54 zsh-4.2.5 -rw--- 1 john john1468 2005-09-20 09:54 zsh_4.2.5-19_amd64.changes -rw--- 1 john john 2119662 2005-09-20 09:54 zsh_4.2.5-19_amd64.deb -rw--- 1 john john 338405 2005-09-20 09:54 zsh_4.2.5-19.diff.gz -rw--- 1 john john 675 2005-09-20 09:54 zsh_4.2.5-19.dsc -rw--- 1 john john 2624122 2005-09-20 09:54 zsh_4.2.5.orig.tar.gz -rw--- 1 john john 672170 2005-09-20 09:54 zsh-doc_4.2.5-19_all.deb -rw--- 1 john john 865214 2005-09-20 09:54 zsh-static_4.2.5-19_amd64.deb /tmp/test/pkgs % This only seems to occur in specific directories, though I have not yet determined whath distinguishes them from others (/usr/local/bin is fine though /usr/local/lib/site_perl isn't). The problem is not limited to zsh, though I haven't done a complete test of all programs for example (running from tcsh): /tmp/test/pkgs/zsh-4.2.5 > dpkg-buildpackage dpkg-parsechangelog: failure: tail of debian/changelog died from signal 11 dpkg-buildpackage: unable to determine source package is Running as root, or through sudo, is sucessful. The same with zsh and the change directory issue. Has anyone experienced this before who can offer some help? The likely course of action for me is to go back to the 32-bit debian or to try another 64bit distribution. However, I am willing to try to diagnose this for a little while.
