Hi. Thank you for your report. I'll look at the possible cause. *** Bug 1150995 has been marked as a duplicate of this bug. *** I'm able to reproduce the issue. The assert is triggered when the server doesn't respond and the query times out. Due to change in next_origin() function parameters in dighost.c our downstream patch was causing the crash. I will fix it in F21, but since upstream recently rejected the patch, I'm going to drop it in rawhide. Fixed in: bind-9.9.6-6.P1.fc22 bind-9.9.6-6.P1.fc21 Is the update for F21 going to be created in bodhi? (In reply to Michael Cronenworth from comment #6) > Is the update for F21 going to be created in bodhi? Sure. I just didn't want to push update with a single issue fixed. bind-9.9.6-6.P1.fc21 has been submitted as an update for Fedora 21. https://admin.fedoraproject.org/updates/bind-9.9.6-6.P1.fc21 Package bind-9.9.6-6.P1.fc21: * should fix your issue, * was pushed to the Fedora 21 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing bind-9.9.6-6.P1.fc21' as soon as you are able to.

Created attachment 967094 [details] core dump from systemd-coredump Description of problem: On certain cases (involving a SERVFAIL response and possibly a timeout), /bin/host can die with SIGABRT due to an assertion failure. Version-Release number of selected component (if applicable): bind-utils-9.9.6-4.fc21.i686 bind-libs-9.9.6-4.fc21.i686 How reproducible: Run /bin/host against a suitably bad domain name and a suitable DNS server. My case is `host tracker.istole.it 192.168.1.1`, where 192.168.1.1 is a residential gateway running dnsmasq. Actual results: $ host tracker.istole.it 192.168.1.1 name.c:2445: REQUIRE((((source) != ((void *)0)) && (((const isc__magic_t *)(source))->magic == ((('D') << 24 | ('N') << 16 | ('S') << 8 | ('n')))))) failed, back trace #0 0xb750061f in ?? #1 0xb7500545 in ?? #2 0xb762644f in ?? #3 0x80502e4 in ?? #4 0x80503ba in ?? #5 0x805062b in ?? #6 0x8055fad in ?? #7 0xb7528828 in ?? #8 0xb71a0313 in ?? #9 0xb6ec5c2e in ??
