I think it's very unlikely indeed that this is a Launchpad bug, and we're not here to go on fishing expeditions for you testing random things. qemu/kernel developers are generally better placed to be able to bisect this sort of thing. Of course you can reopen this if there turns out to be some evidence that this is in fact a Launchpad bug.

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
