Crash on release build but not on dev build

[chencoh]

Hi guys,
I have a scene with a terrain, race track and 4 cars.
The game runs great on the editor and a development build but on a release build the

game crashes when the camera renders a specific area (part terrain and part track).
Here’s the logcat:

I could really use your help interpreting the log and fixing the crashes (hopefully).
if there’s any other information I can provide please ask.
Any help is appreciated!

No one knows? Even some general pointers for debugging it would be appreciated.
