-> https://bileto.ubuntu.com/#/ticket/2055 (xenial and yakkety currently building) I need to stop for today but if someone has time please check if 5.4 backport is possible. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtdeclarative-opensource- src in Ubuntu. https://bugs.launchpad.net/bugs/1630906 Title: QML segfault on arm64 due to builder kernel change Status in linux package in Ubuntu: Confirmed Status in online-accounts-api package in Ubuntu: New Status in qmenumodel package in Ubuntu: New Status in qtdeclarative-opensource-src package in Ubuntu: New Status in ubuntu-push-qml package in Ubuntu: New Status in unity8 package in Ubuntu: New Status in webbrowser-app package in Ubuntu: New Bug description: Builders were changed from wily to xenial (4.4) kernel for arm64, and likely due to this the following kind of errors started happening: https://launchpadlibrarian.net/288487533/buildlog_ubuntu-yakkety-arm64 .ubuntu-push-qml_0.1+15.10.20150826.1-0ubuntu2_BUILDING.txt.gz They happen when executing QML code. I've ruled out that reverting to previous qtbase and qtdeclarative versions don't affect this, so it's not coming from a Qt change. I've also verified there's no problem eg on our Bq tablet running the same tests on xenial+overlay. There are currently no found changes at least in Qt upstream to backport arm64 related fixes. Cause is unknown. But the same problem is there on vivid, xenial and yakkety builds: https://launchpadlibrarian.net/288516465/buildlog_ubuntu-yakkety-arm64.online-accounts-api_0.1+16.10.20161006.1-0ubuntu1_BUILDING.txt.gz https://launchpadlibrarian.net/288515705/buildlog_ubuntu-xenial-arm64.online-accounts-api_0.1+16.04.20161006.1-0ubuntu1_BUILDING.txt.gz https://launchpadlibrarian.net/288515510/buildlog_ubuntu-vivid-arm64.online-accounts-api_0.1+15.04.20161006.1-0ubuntu1_BUILDING.txt.gz This means it does not matter if it's Qt 5.4 or 5.6, GCC 4.9, 5 or 6, or glibc 2.21, 2.23 or 2.24.
