My Wikitude-built app is crashing. I have very little information except for this logcat:

My build process is quite the Frankenstein: I have a bunch of C++ code I compile with Android Studio into a native library called by C# code from Unity as a Wikitude plugin. However, it looks like the error is mostly traced back to Wikitude code, so I thought I could ask an expert to see where to go.

I found that by commenting out different parts of my code, the error regularly would or wouldn't happen. I'm pretty sure I'm doing something with my unmanaged C++ code that corrupts memory. It's not a Wikitude issue.

Thanks,

Mark
