For example:</p> <p><a rel="nofollow" href="https://launchpad.net/ubuntu/+source/krdc/4:23.08.3-1ubuntu1">https:/<wbr />/launchpad.<wbr />net/ubuntu/<wbr />+source/<wbr />krdc/4:<wbr />23.08.3-<wbr />1ubuntu1</a><br /> <a rel="nofollow" href="https://launchpad.net/ubuntu/+source/qmlkonsole/23.08.3-1ubuntu1">https:/<wbr />/launchpad.<wbr />net/ubuntu/<wbr />+source/<wbr />qmlkonsole/<wbr />23.08.3-<wbr />1ubuntu1</a><br /> <a rel="nofollow" href="https://launchpad.net/ubuntu/+source/haruna/0.12.3-1">https:/<wbr />/launchpad.<wbr />net/ubuntu/<wbr />+source/<wbr />haruna/<wbr />0.12.3-<wbr />1</a></p> <p>These are failing due to a segmentation fault in /usr/lib/<wbr />libexec/<wbr />kf5/kconfig_<wbr />compiler_<wbr />kf5 at build time. That binary is provided by src:kconfig</p> <p>This failure is new and did not occur before the builder switch to bos03 with the same kconfig version and build.</p> <p>Likewise test no-change rebuilding kconfig also fails, as kconfig invokes /usr/lib/<wbr />libexec/<wbr />kf5/kconfig_<wbr />compiler_<wbr />kf5 in its build time tests.</p> <p><a rel="nofollow" href="https://launchpad.net/ubuntu/+source/kconfig/5.112.0-0ubuntu2">https:/<wbr />/launchpad.<wbr />net/ubuntu/<wbr />+source/<wbr />kconfig/<wbr />5.112.0-<wbr />0ubuntu2</a></p> <p>Disabling the tests would be futile, as we would just allow a new version of the segfaulting kconfig_<wbr />compiler_<wbr />kf5 to publish, still leaving much of KDE (and some other) source packages unbuildable.</p> <p>In case you are wondering if this is caused by some change in the noble dev release toolchain, that can be demonstrated to not be the case test rebuilding kconfig on mantic where these issues never manifested.</p> <p><a rel="nofollow" href="https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/4979/+sourcepub/15413039/+listing-archive-extra">https:/<wbr />/launchpad.<wbr

(segfault) as in noble, whereas before the builder switch this was not the case.</p> <p>Again I cannot stress how critical an issue this is for several Ubuntu flavours.</p> <p>Thanks in advance for any assistance or solution you can bring.</p> <p>Rik Mills<br /> Kubuntu dev<br /> MOTU</p></div> <div class="portlet"> <h2>Question information</h2> <div class="yui-g"> <div class="yui-u first"> <div

For example:\n\nhttps://launchpad.net/ubuntu/+source/krdc/4:23.08.3-1ubuntu1\nhttps://launchpad.net/ubuntu/+source/qmlkonsole/23.08.3-1ubuntu1\nhttps://launchpad.net/ubuntu/+source/haruna/0.12.3-1\n\nThese are failing due to a segmentation fault in /usr/lib/libexec/kf5/kconfig_compiler_kf5 at build time. That binary is provided by src:kconfig\n\nThis failure is new and did not occur before the builder switch to bos03 with the same kconfig version and build.\n\nLikewise test no-change rebuilding kconfig also fails, as kconfig invokes /usr/lib/libexec/kf5/kconfig_compiler_kf5 in its build time tests.\n\nhttps://launchpad.net/ubuntu/+source/kconfig/5.112.0-0ubuntu2\n\nDisabling the tests would be futile, as we would just allow a new version of the segfaulting kconfig_compiler_kf5 to publish, still leaving much of KDE (and some other) source packages unbuildable.\n\nIn case you are wondering if this is caused by some change in the noble dev release toolchain, that can be demonstrated to not be the case test rebuilding kconfig on mantic where these issues never manifested.\n\nhttps://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/4979/+sourcepub/15413039/+listing-archive-extra\n\nThis fails in exactly the same way (segfault) as in noble, whereas before the builder switch this was not the case.\n\nAgain I cannot stress how critical an issue this is for several Ubuntu flavours.\n\nThanks in advance for any assistance or solution you can bring.\n\nRik Mills\nKubuntu dev\nMOTU\n", "status": "Answered", "language_link": "https://answers.launchpad.net/api/devel/+languages/en", "owner_link": "https://answers.launchpad.net/api/devel/~rikmills", "assignee_link": null, "answerer_link": null, "answer_link": null, "date_created": "2023-12-08T11:37:31.986953+00:00", "date_due": null, "date_last_query": "2023-12-10T10:19:12.777890+00:00", "date_last_response": "2024-03-19T13:08:14.051312+00:00", "date_solved": null, "target_link": "https://answers.launchpad.net/api/devel/launchpad", "messages_collection_link": "https://answers.launchpad.net/api/devel/launchpad/+question/708661/messages", "http_etag": "\"db90c84dc2901d8e9857c9f393facbfb37f5a098-0ac609540bc1763922cd325899b926c56c361fc3\""}};</script> </body>  </html>
