Bug#210840: (no subject)
Subject: libc6: "Inconsistency detected..." and segfaults on 2.6?
Followup-For: Bug #210840
Package: libc6
Version: 2.3.2.ds1-10
Severity: important
I have found this "Inconsistency detected by ld.so" bug few times
on 2.6 kernels using both dual-processor server machine and SiS-chipset
based laptop.
It doesn't seem to depend on nVidia openGL drivers as suggested by
http://www.mail-archive.com/debian-glibc@lists.debian.org/msg07657.html.
(Or it is another bug.)
On every system I had this problem, I also had unexpected segfaults of
dynamically linked libraries (libdbd-pg-perl in postgresql_autodoc on laptop,
libg2c0 on a server).
Downgrading to Debian Stable was the only way I found to fix the problem.
Here is the transcript summarizing my recent observations:
