I've managed to reproduce the crash 3 consecutive times, like this: - installed dnsmasq on the host (ubuntu 10.04 64bit), and started it like this:
/usr/sbin/dnsmasq -d -x /var/run/dnsmasq/dnsmasq.pid -udnsmasq -7 /etc/dnsmasq.d,.dpkg-dist,.dpkg-old,.dpkg-new --dhcp- option=3,172.16.21.253 --dhcp-script=/tmp/myscript.sh - myscript.sh contains the following: #!/bin/bash sleep 10 echo $@ exit 0 - ran 4 ubuntu guests in KVM - logged in on every guest, and ran the following command from console: while [ true ]; do dhclient3 eth0 ; done (this basically renews the lease on the guests all the time, generating some load for dnsmasq) After ~10 minutes dnsmasq crashed with "*** glibc detected *** /usr/sbin/dnsmasq: double free or corruption (fasttop): 0x00000000006a1040 ***" (this happened 3 times out of 3 runs). After installing the package from -proposed, I tried once more, same setup but it did not crash. It's been running like this for >30 minutes. I'll let it run for a couple of hours to see if anything happens. -- You received this bug notification because you are a member of Registry Administrators, which is the registrant for Debian. https://bugs.launchpad.net/bugs/674645 Title: occasional crashes: glibc detected double free or corruption _______________________________________________ Mailing list: https://launchpad.net/~registry Post to : registry@lists.launchpad.net Unsubscribe : https://launchpad.net/~registry More help : https://help.launchpad.net/ListHelp
