Android

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)"

    the sigsegv 11 error occured to my project after upgrading the project from 4.5 to 5 (up to 5.0.2) on nexus s device.
    Now its gone after updating to 5.1.2 (from 5.0.2)!

    Maybe related: I am also using lots of mobile particle materials (mostly "multiply" not sure if i use "alpha blended" as well) maybe "sebek89" repro case was my problem as well.

    For me its fixed with the update!

    Forgot to add that for that repro it happenes on all devices (different GPU vendors) I've tested this (Sony Xperia Z, Galaxy S4, Lenovo A820, Acer Iconia A1-810).

    I have 100% repro for that crash, even on latest 5.1.1p1:

    1) Create material with Particle/Alphablended or Mobile/Particle/Alphablended
    2) Attach this material to normal model (even built-in cube)
    3) Place two or more such objects on the scene
    4) Enable dynamic batching

    Result: crash on android device.

    If you change the shader or disable dynamic batching the crash doesn't occur. Please fix that ASAP!

    Just seen this crash on a brand new Galaxy Note 4 with Lollipop 5.0.1 building with Unity 5.0.1f1. Works fine on our other test devices (Xperia Z2, Nexus 7 [original], Galaxy S4 and Note 8).
    Have tried changing OpenGL settings and checking / unchecking 32-bit display buffer in Android Player Settings but no luck.

    adb output before crash:
