From that trace, it looks like it is in this code in dhcp_config_free() when it makes the free() call:
#ifdef HAVE_DHCP6 if (config->flags & CONFIG_ADDR6) { struct addrlist *addr, *tmp; for (addr = config->addr6; addr; addr = tmp) { tmp = addr->next; free(addr); } } #endif That *seems* Ok at first look, right? I do like the while() loop above it better :) I do see a potential issue when IPv6 addresses are added to this list, but I think it would just cause a memory leak, search for CONFIG_ADDR6 in that file. Guess I'll have to send that to the list, I can't unsee it now. You might just need to step through that code to see what 'addr' actually is. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2026757 Title: dnsmasq on Ubuntu Jammy crashes on neutron-dhcp-agent updates To manage notifications about this bug go to: https://bugs.launchpad.net/ironic/+bug/2026757/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
