    Hello
    I have an exception that occurs once in a while when I start Unity on Android.
    In my app, I place images on a cube.

    Unity version: 2017.1.1p2
    Mobile device: Nexus 6p
    Exception:
    Code (CSharp):
    1. A/libc: Fatal signal 7 (SIGBUS), code 2, fault addr 0xbd5c3000 in tid 19389 (UnityMain)

    I also used android ndk addr2line to get the methods:
    Code (CSharp):
    1. try_get_word
    2. dump_memory
    3. dump_memory_and_code_common
    4. dump_memory_and_code_signal
    5. NativeRuntimeException::signal_handler(int, siginfo*, void*)
    6. ApiGLES::CreateBuffer(gl::BufferTarget, long, void const*, unsigned int)
    7. DataBufferGLES::Upload(unsigned int, unsigned int, void const*)
    8. ConstantBuffersGLES::UpdateBuffers(MonoOrStereoscopicEye, bool)
    9. GfxDeviceGLES::BeforeDrawCall()
    10. GfxDeviceGLES::DrawBuffers(GfxBuffer*, VertexStreamSource const*, int, DrawBuffersRange const*, int, VertexDeclaration*, ShaderChannelMask)
    11. Skybox::RenderAllFaces(Material*)
    12. GenerateEnvironmentData(int, float*)
    13. EnlightenRuntimeManager::UpdateEnvironmentLighting()
    14. EnlightenRuntimeManager::Update()
    15. PlayerLoop()
    16. UnityPlayerLoop()
    17. nativeRender(_JNIEnv*, _jobject*)
    Can anyone help me?

    Thanks a lot!
