After today series of updates my x86_64 test box started seriously misbehave. For example: # iptables-restore /etc/sysconfig/iptables *** glibc detected *** iptables-restore: free(): invalid pointer: 0x00002aaaaaac7150 *** Aborted # runuser -s /bin/bash - nobody -c mDNSResponder *** glibc detected *** runuser: double free or corruption (out): 0x00002aaaaaac7650 *** # service xfs status xfs dead but pid file exists and many other things. Some fail silently, other will complain like above. Pointers indeed look a bit strange. Interestingly enough /sbin/iptables-restore was installed on 2004-Nov-12 and 'ldd /sbin/iptables-restore' shows only libdl.so.2 => /lib64/libdl.so.2 (0x00000033f4b00000) libc.so.6 => /lib64/tls/libc.so.6 (0x00000033f4600000) /lib64/ld-linux-x86-64.so.2 (0x00000033f4400000) wher all three pieces were installed yesterday afternoon and a machine was running, and rebooting, a few times without any ill-effects until new rawhide packages were retrieved. 'rpm -V' does not report any troubles neither for 'iptables' nor for 'glibc'. A sudden hardware failure does not seem to be likely as another Linux installation on the same box runs just fine. A swap space is common to all installations. Booting older kernels also does not change anything. Today packages look like the most probably cause but I do not see on that list anything obvious. Oh, and x86 test system, updated to the same level, is not doing anything strange. I would file a bug report but I am somewhat at loss about what. Anybody seeing something similar? Michal
