I'm not sure if it is related, but I've encountered test failures in my mediascanner2 silo for dbus-cpp code that previously ran without issue:
https://launchpadlibrarian.net/281863370/buildlog_ubuntu-yakkety- arm64.mediascanner2_0.112+16.10.20160831-0ubuntu1_BUILDING.txt.gz It also failed on armhf, powerpc, and ppc64el, but passed on i386, amd64 and s390x. The branches in the silo make no changes to the code being run by the failing tests. I'll report back after I've investigated further. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mtp in Ubuntu. https://bugs.launchpad.net/bugs/1618390 Title: dbus-cpp crash on arm64 in core::dbus::Object::get_property Status in Canonical System Image: New Status in dbus-cpp package in Ubuntu: New Status in location-service package in Ubuntu: New Status in mtp package in Ubuntu: New Bug description: Requests to location service cause crashes on arm64: $ system-image-cli -i current build number: 23 device name: frieza_arm64 channel: ubuntu-touch/staging/ubuntu last update: 2016-08-30 09:13:12 version version: 23 version ubuntu: 20160830 version device: 20160824.0 version custom: 20160830 Steps: * flash the above channel (remember --device frieza_arm64) * go to a scope using location * refresh == Stacktrace ================================= #0 0x0000007f978d4328 in std::_Sp_counted_base<(__gnu_cxx::_Lock_policy)2>::_M_release() (__val=-1, __mem=0x29) at /usr/include/c++/5/ext/atomicity.h:49 __val = -1 __mem = 0x29 #1 0x0000007f978d4328 in std::_Sp_counted_base<(__gnu_cxx::_Lock_policy)2>::_M_release() (__val=-1, __mem=0x29) at /usr/include/c++/5/ext/atomicity.h:82 __val = -1 __mem = 0x29 #2 0x0000007f978d4328 in std::_Sp_counted_base<(__gnu_cxx::_Lock_policy)2>::_M_release() (this=0x21) at /usr/include/c++/5/bits/shared_ptr_base.h:147 #3 0x0000007f97922a28 in std::__shared_count<(__gnu_cxx::_Lock_policy)2>::operator=(std::__shared_count<(__gnu_cxx::_Lock_policy)2> const&) (this=this@entry=0x8b34558, __r=...) at /usr/include/c++/5/bits/shared_ptr_base.h:678 __tmp = 0x8b34ba0 #4 0x0000007f9792cc64 in core::dbus::Object::get_property<com::ubuntu::location::service::Interface::Properties::State>() (this=0x8b34550) at /usr/include/c++/5/bits/shared_ptr_base.h:867 property = <error reading variable: Cannot access memory at address 0x1fe000001ea41> #5 0x0000007f9792cc64 in core::dbus::Object::get_property<com::ubuntu::location::service::Interface::Properties::State>() (this=0x8b34550) at /usr/include/c++/5/bits/shared_ptr.h:93 property = <error reading variable: Cannot access memory at address 0x1fe000001ea41> #6 0x0000007f9792cc64 in core::dbus::Object::get_property<com::ubuntu::location::service::Interface::Properties::State>() (this=0x8b342c0) at /usr/include/core/dbus/impl/object.h:162 property = <error reading variable: Cannot access memory at address 0x1fe000001ea41> #7 0x0000007f97931c08 in com::ubuntu::location::service::Stub::Stub(std::shared_ptr<core::dbus::Bus> const&) (object=warning: can't find linker symbol for virtual table for `std::_Sp_counted_base<(__gnu_cxx::_Lock_policy)2>' value warning: can't find linker symbol for virtual table for `std::_Sp_counted_base<(__gnu_cxx::_Lock_policy)2>' value ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: libubuntu-location-service3 3.0.0+16.04.20160811-0ubuntu1 [origin: LP-PPA-ci-train-ppa-service-stable-phone-overlay] Uname: Linux 3.10.93+ aarch64 ApportVersion: 2.20.1-0ubuntu2.1 Architecture: arm64 Date: Tue Aug 30 09:39:24 2016 SourcePackage: location-service UpgradeStatus: No upgrade log present (probably fresh install) --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: arm64 DistroRelease: Ubuntu 16.04 Package: mtp-server 0.0.4+16.04.20160413-0ubuntu2 [origin: LP-PPA-ci-train-ppa-service-stable-phone-overlay] PackageArchitecture: arm64 Tags: third-party-packages xenial Uname: Linux 3.10.93+ aarch64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dialout dip plugdev sudo tty video _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1618390/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
