It appears the crash started happening on phones in Mir 0.21, which actually isn't in the stable channel yet. So expect this bug to explode after OTA-11 goes out...
No idea why it would crash though: template <typename ProtobufType> auto make_protobuf_object() { return std::unique_ptr<ProtobufType>{ProtobufType::default_instance().New()}; } Perhaps another manifestation of the Unity8 heap corruption bug 1535297? ** Also affects: mir Importance: Undecided Status: New ** Summary changed: - /usr/bin/unity8:11:std::string::_Rep::_S_empty_rep_storage:mir::client::make_protobuf_object:mir::client::rpc::MirProtobufRpcChannel::on_data_available:operator:_M_invoke + /usr/bin/unity8 crashes in std::string::_Rep::_S_empty_rep_storage() from mir::client::rpc::MirProtobufRpcChannel::on_data_available() ** Changed in: mir Importance: Undecided => High ** Changed in: mir (Ubuntu) Importance: Undecided => High ** Also affects: canonical-devices-system-image Importance: Undecided Status: New ** Summary changed: - /usr/bin/unity8 crashes in std::string::_Rep::_S_empty_rep_storage() from mir::client::rpc::MirProtobufRpcChannel::on_data_available() + Unity8 crashes in std::string::_Rep::_S_empty_rep_storage() from mir::client::rpc::MirProtobufRpcChannel::on_data_available() -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1579957 Title: Unity8 crashes in std::string::_Rep::_S_empty_rep_storage() from mir::client::rpc::MirProtobufRpcChannel::on_data_available() Status in Canonical System Image: New Status in Mir: New Status in mir package in Ubuntu: New Status in unity8 package in Ubuntu: Incomplete Bug description: The Ubuntu Error Tracker has been receiving reports about a problem regarding unity8.
