Crash in ArPresto_update(), ArSession_update(): java.lang.Error: signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)

mikatzou commented 3 years ago

SPECIFIC ISSUE ENCOUNTERED

Our app is encountering a random crash issue, while ARCore is active. It appears to occur randomly, and is most reproduceable by simply leaving the app running while the camera & ARCore are running. Leaving it running for 15 minutes will repro about 25% of the time. I added some additional logs before and after ARCoreAndroidLifecycleManager calls ArPresto_update() from OnEarlyUpdate(), and it looks like this is happening within that call. I haven't been able to trace deeper than that though. We have seen this on multiple devices, but the logs I've included are from Pixel 4 XL. Attached logs include stack trace and nearby memory.

VERSIONS USED

Unity: 2018.28.4f1
ARCore SDK for Unity: 1.20.0
Device manufacturer, model, and O/S: Google, Pixel 4XL, Android 11 (We have seen this issue on other devices as well)
Google Play Services for AR (ARCore): Packages: versionName=1.22.203220503 Hidden system packages: versionName=0 Active APEX packages: Inactive APEX packages: Factory APEX packages: On Windows, use: adb shell pm dump com.google.ar.core | findstr /i "packages: versionName" On macOS, use: adb shell pm dump com.google.ar.core | egrep -i versionName\|packages:
Output of adb shell getprop ro.build.fingerprint: google/coral/coral:11/RQ1A.210105.003/7005429:user/release-keys

STEPS TO REPRODUCE THE ISSUE

Leave camera & ARCore running, wait up to 15 minutes.
Repro rate appx 25%.

WORKAROUNDS (IF ANY)

None

czadamToptal commented 3 years ago

We have very similar crash report, happens randomly in the app. android_crash.txt

Unity: 2018.4.28 ARCore SDK for Unity: 1.22.0 Device manufacturer, model, and O/S: Google, Pixel 3a XL, Android 11 (We have seen this issue on other devices as well) Google Play Services for AR (ARCore): 1.22

fredsa commented 3 years ago

Since the issue reproduces fairly easily (i.e. leave the app running for 15 minutes), could you try building the app using:

The latest ARCore SDK for Unity
The latest 2018.4 (https://unity3d.com/get-unity/download/archive) release of Unity, or preferably the latest 2019.4 or 2020.4 release

Even if you're not able to ship your app using 2019.4/2020.4, it would still be useful to quickly rule out any issues with the specific version of Unity and our the ARCore SDK for Unity.

maren-mclean commented 3 years ago

Coming to this as we started having issues after updating ARFoundation versions when updating Unity versions with the application eventually crashing after some seemingly random time interval and this is our exact bug as well.

VERSIONS USED

Unity: 2019.4.28f (latest LTS)
ARCore SDK for Unity: 1.19 (provided under ARFoundation 2.1.18 - verified 2019.4.28f release)

It may be of relevance so I am adding this here, we are also receiving this error every frame of our application's runtime in Unity's console since updating: session_lite_c_api.cc:153] operator(): width <= 0 and have been unable to find its origin in our application, but it points to ARCore support libraries.

Running through several iterations and expanding log verbosity it is possible to sometimes get a more detailed error.

This crash produced an acknowledgement of a null pointer dereference with the same error as above. This was produced on the non-latest Unity version as it was a previous crash error I noticed that had better details. tombstone_log_2.txt

Where as this next crash was a hard crash with no tombstone cleanup and the log could only be copied from the android logcat feed, but it produced an ARCore Native Error along with a similar error as above, but failing internally within a different call stack (not within ARSession_Update it looks like, but an event that was being delivered, potentially from that area). It was produced on latest versions, just for clarification. unity_logcat_crashlog_3.txt crashlog_3.txt (Cleaned it up to remove the Unity logcat text)

Since this also points to an ARCore Native error
