This is looking like a case of the code being miscompiled under optimisation. To reproduce, build mediascanner2 using the "RelWithDebInfo" build type and then run:
./test/test_dbus --gtest_filter=*filter_codec The test program segfaults when calling Variant::as<std::string>() on a variant that should have been initialised by reading out of a Message::Reader. When compiling with the "Debug" build type, the test program completes without error. I can probably solve the immediate problem in mediascanner2 by disabling optimisation for the affected file. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1621002 Title: Mediascanner2 test failure on yakkety/{armhf,arm64,ppc64el} with latest dbus-cpp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dbus-cpp/+bug/1621002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
