Crash on splash screen [Universal 8.1 Phone / Lumia 520]

I've got a bit of a strange issue with a couple games that will load and run fine on most devices but are crashing sometime during or immediately following the splash screen.

This happens for me exclusively on a Lumia 520 test device running WP8.1. A lumia 630 runs the same games just fine. Current using Unity 5.3.4p6.

Unfortunately I don't have much insight, as it appears this error is deep in native code. The output is the following:

No idea where to start looking for the source of this - I've done several games with the same methods and they always seem to run fine (albeit a bit slow) on the 520.

 

Thanks for the reply. I tried this again - unfortunately it cannot seem to locate the symbols. It is searching for qcdx9um8930.pdb and does not locate it on the MS symbol server.

I'll try to isolate it to a small project and then hopefully submit that as a bug report.

 

We are facing the same (or very similar) issue on Lumia 620, callstack is basically identical. Our game is built with Unity 5.3.4p6 as well. Did you make any progress with this?
