qemu isn't involved. We intentionally run armhf builds on an arm64 kernel (with an appropriate personality set) because this allows us to make denser use of our build resources; I don't expect this to change.

I did run the test under strace/valgrind, I can't do much more testing, but I hope the logs can be useful for you https://launchpad.net/~costamagnagianfranco/+archive/ubuntu/locutusofborg-ppa/+build/13169431 https://launchpadlibrarian.net/331134898/buildlog_ubuntu-artful-armhf.notmuch_0.25-2ubuntu1_BUILDING.txt.gz You can see the strace/valgrind outputs between "BEGIN" and "END" keywords To manage notifications about this bug go to: https://bugs.launchpad.net/launchpad-buildd/+bug/1707409/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
