Random Crashes (SIGSEGV) on Android Huawei devices - (maybe linked to AssetBundles and/or Textures)
Hello,
We're having a lot of crash reports of the same type from the Google Play Console showing some errors causing the app to crash, but only for devices of a specific brand (Huawei).
One example of report is attached below. Basically, all the reports have the same shape: the exception can occur at any place in our code, then it always results in the same "java.lang.Error" in UnityMain process.
The weird thing is (and I don't think it's a coincidence) the complete list of devices shows exclusively devices of the Huawei brand.
Any idea of what could cause such errors on specific devices?
Thanks a lot!

Hello,
A few updates - I've desymbolicated the above reports and it seems that the crash is linked to Unity's management of asset bundles & textures.
Among all the reports I got, there are 2 different stack traces that end up in the same crash:
java.lang.Error: signal 11 (SIGSEGV), code -6 (?), fault addr 00001058

Has anyone any idea of why these crashes could occur, and only on the specific abovementioned devices (Android 8 / Huawei)?
Thanks a lot,
Hello, just wanted to bump this as I am experiencing the same thing. Crashes only on Huawei devices running Android 8 - 9. Play console shows the same "java.lang.Error: signal 11 (SIGSEGV), code -6 (?)" I am on unity version 5.6.5.
Hello,
Glad to see I'm not the only one with this error. I realized I did not precise my Unity version in my original post => i'm using Unity 5.5.5p1.
After a few tests, I don't think it comes from one of our SD$$anonymous$$s.
I suspect some very specific assets in one of our scenes, maybe a mesh or a texture somewhere.
I think the error occurs somewhere in an async process since the crash report seems to be triggered randomly at different part of my code that do nothing special regarding the crash, but are located not far from each other.
Sadly I don't have any other info for the moment... If anyone has an idea, that'll be much appreciated!
Hi, our game using Unity 5.6.6p1 have the same problem, we did found that all come from Huawei devices and It happen when load assetbundle, but still not idea how to fix it yet.
