"signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)" (792333)

Unity Engine

Hey,

So on our most recent game we’re getting a high crash rate on Google Play. Our general crash rate is 0.77% but on Android 10 it’s higher, about 1.46% (above the bad behaviour threshold). We have a bunch of similar crashes all signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), but the two below are the most common.

We’ve spent a couple of weeks trying to work out what’s going on and have tried a bunch of different things, but in all honesty I don’t really know where to start, so was wondering if anyone could give us a pointer. We’re on 2019.3.13f1. We’ve updated all our plugins to the most recent versions (Google Play Games, IronSource, PlayFab etc) and this hasn’t made a difference to the crash rate.

We haven’t been able to reproduce these issues locally and we’re not getting reports from players (we have quite a tight reddit community, so I would expect at least some reports if it was disrupting gameplay), so I don’t think the crashes are player facing. I’m wondering if the game crashes silently when you resume playing or when you close it.

Any help is massively appreciated.

So I’ve done addr2line (heh, didn’t know that was a thing) and this is what’s come out. So it looks like a shader issue if I’m reading that right?

We have a lot of similar crashes, with the latest 2019.2 or 2019.3. Nobody really cares. Some of the games has 0.70% crash rate, other crossed bad behaviour with 1.25% or so. Downloads are constantly drops. Very sad, that Unity Team doing nothing for this ;(

In our games we have AdMob (and Chartboost + Applovin mediation) and Unity Ads. Ads and ads plugins - all the latest versions. Unity 2019.3.14f + Api Level 29

Updated just yesterday, still no success, same crashes everywhere.

We tried to fix it with “backup prefs” solution (.xmls and androidmanifest), but this is does not worked.

Are you sure you’re using correct path for symbols, the resolved stacktrace doesn’t look correct.

Hi Tomas, thanks very much for the reply. We followed the instructions on https://support.unity3d.com/hc/en-us/articles/115000292166-Symbolicate-Android-crash, but needed to use a different path to what’s on there and used the wrong one.

We tried again using the following which I think is the correct symbol file.

Does this look correct and does it mean anything to you if so?

Lines [1-15] looks correct, everything else doesn’t look correct. Can you copy paste unresolved stacktrace?

This is the one.

so as you see only frames from [#00 … #06] are from libunity.so, others are not, so you can’t use libunity symbols on them.

Sadly, It’s not clear what exactly is wrong here, it seems it crashed on application start.

9

Re:libunity. Are you saying here that everything beyond frame #06 is from before Unity is invoked, and so not relevant, or that it could be relevant but we can’t see what it is? If it’s from before unity is invoked and unity is being killed within the first lines, what could be causing it to crash so early?

Here’s the second most common crash which I assume is connected.

Everything is relevant, the problem it’s not enough information… It’s sad that google doesn’t provide logcat together with crash stacktrace.

Do you have information about which devices produce stacktrace containing

NativeRuntimeException::install_signal_handlers()

11

They’re all Android 10 devices, main culprits are Pixel 4 XL, Pixel 3, Pixel 2, Galaxy S9.

12

I did some digging, and there is one place which might be suspicious and might cause a crash, but it would be a blind fix since there’s no repro.

13

We’re happy to try anything at this point!

14

Is this fix something we can try out? Or will it be coming out in a new version of Unity?

15

The fix has to first land into our master branch, only then we can backport it to previous Unity versions, assuming it’s not causing any regressions. Sadly it might take few weeks to happen, and another few weeks for the new Unity release

16

Anything you can share regarding the cause of the issue or a way to find a workaround?
Our crash rate also skyrocketted on our live version and mostly points at this stack.

17

Without the repro case, it’s hard to say. But please provide Unity version and stacktraces where this happens, this will help identify if this is a regression.

The specific code above haven’t been touched for several years, so I doubt the issue is there, there’s probably an external factor. Like Android API level upgrade.

If it’s really Android API problem, I guess you could always lower the target API level

18

Yes, we are also have unacceptable tons of crashes in several games built with Unity 2019.3. We are always stick with the latest API level 29, so I saw hope in your post. Yesterday our team have uploaded game built with the latest 2019.3 and API level 28 and I confirm that it does not help, same crashes. It does not make a sense.

Unity Technologies team, please do something about this, because the latest releases of Unity is not good for Android Developer, 2018.4, 2019.2, 2019.3 - have different problems, but they share unacceptable level of crashes.

FYI, few days ago Google just mailed a letter to all developers about incoming changes, so they won’t accept API 28 soon, only 29 will be acceptable since August for a new apps, and since November for an updates.

19

Can you share more information, like stacktraces?

20

We should raise verbosity level and update the game we are testing on, will let you know later.
