Bug#765562: libc6: Update of libc6 breaks at least ntp and http-mode in aptitude - segfault
Package: libc6
Version: 2.13-38+deb7u5
Severity: important
Dear Maintainer,
*** Please consider answering these questions, where appropriate ***
* What led up to the situation?
System upgrade (by aptitude) for a stable/wheezy and
proposed-updates.
The machine did run fine before the upgrade regarding all mentioned
programs and processes
* What exactly did you do (or not do) that was effective (or
ineffective)?
I tried to (re-)start the ntp(d)-service and an "aptitude update"
* What was the outcome of this action?
Segfaults
* What outcome did you expect instead?
Running programs :-).
*** End of the template - remove these lines ***
I do have several systems which did not(!) experience this problem!
I also have four (very similar) systems that all(!) show these
symptoms; they are all IBM x-Series 335 machines. So it might be
hardware-dependend, especially which CPU-type is used!
Result of "aptitude update"
0% [Working]E: Method http has died unexpectedly!
E: Sub-process http received a segmentation fault.

with the following lines in /var/log/syslog:

Trying to "/etc/init.d/ntp start" the ntp process leaves me without a
running ntp an generats the following line in /var/log/syslog:
