Simplest set of steps to reproduce:
1) Start the program
1) Select one of the presets from the toolbar
3) Increase reflections depth to 6 or above
4) Render

Program returns multiple error message boxes;
"Error: Error during compilation of OpenCL program
OpenCL Build Log:"
"Error: Cannot enqueue writing OpenCL input buffers"
"Error: OpenCL command queue cannot be created!"

When these are acknowledged, the program is still functional, but OpenCL cannot be used until after restart.  It's possible to disable OpenCL in preferences and render using CPU, though.

This behaviour is seen on my home system - Core i7-4770K with 32GB RAM, Nvidia GTX 1080ti , and Windows 10 64 bit.

In contrast, on my work system, there is no error and the scene renders as expected with the higher reflection value - Core i5-4300U with 8GB RAM, and Intel HD 4400 graphics, also Windows 10 64 bit.

Here's the 'Info' output from the working system:

Sorry - forgot to specify : on my home system, if I leave the reflections depth at its default value of 5, there's no error and the scene renders as expected.  It's only setting it to a value of 6 or above that gives an error.

Thanks for reporting this problem. It's reproducible and happens only when is increased reflections depth and reflectance and transparency is set to zero in default material. If you increase reflectance (to be not zero), then you can use higher depth.
I have just found what is wrong in the code, so error will be fixed very soon.
