Please, this still happening
Unity 2017.4.11f1 on Android 4.4.2

Similar issue here. I only noticed in Android 4.4 (Emulator). Running in my device with 8.1.0 without a problem.

The App loads perfectly but after a while it crashes, happening when the background music loops... Please help!

This part of code lead to "signal 11 (SIGSEGV), code 1" error on Android on Unity 2018.1.0, because it was invoked by Async Task of network socket callback (not in main thread).
And moving to main thread by "UnityMainThreadDispatcher.Instance().Enqueue( ... ); " did not work.

I have changed my app logic to fix it.

Still suffering.... unity version 2018.2.0f2

Yeah, it happens for me too - I upgraded Unity from 2017.3.1p1 to 2018.2.5f1. I had to reimport and adjust Text Mesh Pro as it is part of Unity since 2018.1 - done.
Working in editor perfectly.
IOS build - working perfectly.
Android build is showing logo and then app freezes (and now crashes) giving in logcat:

08-27 17:44:41.308 21849-21883/? E/CRASH: signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 00000000

* turning off multithread rendering - did not helped,
* turning on all build architectures - did not helped,
* updating firebase SDK - did not helped

2018.2.5f1 as well. In my case, I think the cause has to do with running Firebase transactions and then starting some coroutines/enabling/disabling UI elements.

Also getting this error on some devices (Android 6.0 for example). Game made with Unity 2018.1

2017.3.0f3 getting same crash, and looks like this is not a device specific, I've got my project running fine until one time... this happens and now happening often at random time... I have other projects which running without issues with same shaders, build and quality settings...

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
