Need help debugging an Android crash with no stack trace

I'm trying to help a client with an Android port, but I'm not really an Android expert. When we build the game in development mode, it will consistently crash after about 10 seconds of gameplay (it only crashes in-game, not in the menu screen). When we build in release mode, the crashes go away. The game is already released for iOS and does not crash there. Looking at the logcat, it just says WIN DEATH:

How do I debug this? It crashes consistently on three different devices with different amounts of RAM (although they are all Samsung devices), but only in a development build. When I look at the profiler, it doesn't seem like memory or CPU are spiking or anything - levels stay pretty consistent until it crashes.. If the problem is due to resource usage (just a guess), how can I figure out what specifically is the problem?

Any advice would be appreciated because I'm not sure how to get more info - thanks!

 

got exactly the same problem. iOs works perfect, even on an old ipad 3. Got this crash on a galaxy s3 with 1gb and a moto x with 2gb ram. Got this crashes with unity 5.3 and 5.4.

crashes most after scene loading. Im very sad that there is no help for that and the unity guys didn´t check that high numbers of threads here about that problem.
