Re: Segfaults as non-root user

2005-10-19 Thread Hendrik Tews
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?

Bye,

Hendrik Tews

looks like the bug I've seen on my system with random programs, too.
Just look here:

Wiping out my zshrc fixed the ls bug, however, the dpkg-buildpkg error
still remains.  In dmesg:

dpkg-parsechang[19135]: segfault at 00f0 rip 2b7922bb rsp 
7fde93d0 error 4
