After some more debugging/testing, it seems like the problem is indeed caused by compiler optimization. More specifically, LTO. Disabling it seems to have done the trick, and I can't reproduce the segmentation fault anymore.
Basically: ifeq ($(DEB_HOST_ARCH),ppc64el) export DEB_BUILD_MAINT_OPTIONS += optimize=-lto endif on d/rules. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2055151 Title: kea-ctrl-agent segfault in ppc64el dep8 test To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-kea/+bug/2055151/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
