bind-utils-9.8.0-3.P1.fc15.x86_64 This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.

Yay UBS for being incompetent and giving me a public test case... This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. (In reply to comment #5) > That one is a publicly misconfigured nameserver, so should be reproducible > by anyone. Yay UBS for being incompetent and giving me a public test case... Hi. Do you still have this issue on Fedora 18? If yes, can you please include full name-version-release of bind-utils ('rpm -q bind-utils')? I tried: $ host onesource.apollo.ubs.com and $ host onesource.ubs.com with bind-utils-9.9.2-10.P2.fc18.x86_64 and the 'host' binary does not die with SEGV. Thanks! Reported to upstream -> [ISC-Bugs #34870] Patch also prepared and sent... I'll include this fix in Fedora.

Some of my employer's nameservers are broken; they return SERVFAIL for AAAA lookups for some hosts, including pkgs.fedoraproject.org. I therefore expect some strange behaviour... but I *don't* expect 'host' to die with a segmentation fault.
