Android crash: Fatal signal 11 (SIGSEGV) on some devices
On a small number of Android devices app crashes having exhibited very strange behaviour. The behaviour can vary but the result is (almost) always "Fatal signal 11 (SIGSEGV)"

This issue is occurring for a customer using a TECTOY TT-5000i since upgrading my project to 2017.3.0f3.
He opens the app and after some seconds it crashes giving:
java.lang.Error: signal 11 (SIGSEGV), code 128 (?), fault addr 00000000
I have removed all crunch compression and unchecked Multithreaded Rendering as per previously suggested solutions however the error still occurs.

Seems like crunched compression on textures are causing a fatal signal 11 under android (2017.3f3). I've submitted a bug report (#984270).
I can 100% reproduce this issue. Just create a new project, import a texture and set compression to crunched (all default values). Create a new scene and a cube. Last has to use a new material using the imported texture as diffuse texture.
Now make an android build. Use Build System Internal as gradle will crash.
Run app and wait 2-5 seconds. -> Fatal Signal Crash
I use Memu but I also could reproduce it on a Samsung Note 3 and Galaxy S5 mini

Same problem here:
We load our scenes additive asynchronously in a coroutine. It seams the routine gets stucked at 2% progress. After that the following fatal signal occours:

Multithreaded rendering is disabled. We are using 2017.3f3
We don't use Resources.Load in Awake-methods
The scene is big but memory allocations/usage is still ok, no low memory warnings. Problem primarily occours on Memu Emulator but also happens on my Samsung Note 3. On other android devices it doesn't crash

Same here, version 2017.2.0f3 on a Samsung Galaxy S3 Neo.
To resolve the issue I unchecked Multithreaded Rendering, thanks ETHANKENNERLY-GLU for the suggestion. I wonder why this is the default option.

Unity 2017.2.0f3 sometimes crashes if Android property Multithreaded Rendering is left in default checked state. Test scene is a simple canvas with one text and one button.
Device is a low-end Android Phone, Samsung Galaxy S4.
