This seems to be a mix of issues, but the crash itself is caused because android_camera_set_scene_mode gets called after control gets released. In theory the correct result here would be an abort, but it seems assert is not behaving properly, which I'm now investigating why.
Besides that, the release/closing race seems to be actually part of qtubuntu-camera, and not hybris. #0 my_pthread_mutex_lock (__mutex=0x8) at hooks.c:479 #1 0xa9d66f9c in android::Mutex::lock (this=this@entry=0x8) at system/core/include/utils/Mutex.h:112 #2 0xa9d67266 in Autolock (mutex=..., this=0xbef1ba70) at system/core/include/utils/Mutex.h:65 #3 android_camera_set_scene_mode (control=0x0, mode=SCENE_MODE_AUTO) at ubuntu/libhybris/compat/camera/camera_compatibility_layer.cpp:304 #4 0xac3413e4 in android_camera_set_scene_mode (n1=0x0, n2=SCENE_MODE_AUTO) at camera.c:50 #5 0xac37f848 in AalCameraExposureControl::setValue(QCameraExposureControl::ExposureParameter, QVariant const&) () from /usr/lib/arm-linux-gnueabihf/qt5/plugins/mediaservice/libaalcamera.so #6 0xacd1c0fc in AdvancedCameraSettings::setHdrEnabled(bool) () from /usr/share/click/preinstalled/com.ubuntu.camera/3.0.0.387/lib/arm-linux-gnueabihf/CameraApp/libcamera-qml.so #7 0xacd2147c in AdvancedCameraSettings::qt_metacall(QMetaObject::Call, int, void**) () from /usr/share/click/preinstalled/com.ubuntu.camera/3.0.0.387/lib/arm-linux-gnueabihf/CameraApp/libcamera-qml.so #8 0xb6620c74 in QQmlPropertyPrivate::write(QObject*, QQmlPropertyData const&, QVariant const&, QQmlContextData*, QFlags<QQmlPropertyPrivate::WriteFlag>) () from /usr/lib/arm-linux-gnueabihf/libQt5Qml.so.5 #9 0xb662135a in QQmlPropertyPrivate::writeValueProperty(QObject*, QQmlPropertyData const&, QVariant const&, QQmlContextData*, QFlags<QQmlPropertyPrivate::WriteFlag>) () from /usr/lib/arm-linux-gnueabihf/libQt5Qml.so.5 #10 0xb66213f4 in QQmlPropertyPrivate::writeValueProperty(QVariant const&, QFlags<QQmlPropertyPrivate::WriteFlag>) () from /usr/lib/arm-linux-gnueabihf/libQt5Qml.so.5 #11 0xb6621474 in QQmlProperty::write(QVariant const&) const () from /usr/lib/arm-linux-gnueabihf/libQt5Qml.so.5 #12 0xb66995b6 in ??
