Skyboxes cause "not enough frames in stack" error

I’v been updating my game, and everything was working perfect when testing on my iPad. A problem occurred when I added a default Skybox to my scene. I added a Skybox component to the camera, set the camera to render a Skybox. When i attempt to build run from XCode, I keep getting a “not enough frames in stack” error. Any idea what could be causing this? It seems that the Skybox is the only thing causing the problem. Anyone know how I can use a Skybox but not run out of memory?

Please can you file a bug report for this (menu: Help > Report A Bug), ideally attaching the project that shows this problem.

Hi,
There might be various reasons for that and not necessary Skybox is directly involved there.
Unity Manual has dedicated troubleshooting section, which tells how to obtain meaningful stack traces in Xcode and how to interpret them: Unity - Manual: Troubleshooting
