Here are the results:

Laptop (Win 10):
Platform: Intel OpenCL, Device: i7 --> every second application crashes
Platform: Intel OpenCL, Device: Intel HD Graphics 4000 (embedded) --> total crash with  CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR even for a single application
Platform: NVIDIA CUDA, Device: GeForce GT 735M --> tested up to 10 parallel applications without any issue

Workstation (Win 8.1):
Platform: AMD, Device: AMD FirePro W9100 --> works without any problems
Platform: AMD, Device: Intel Xeon CPU --> works without any problems
Platform: Intel OpenCL, Device: Intel Xeon CPU --> every second application crashes
Platform: Experimental OpenCL 2.0 CPU Only Platform, Device: Intel Xeon CPU --> every second application crashes

So, only Intel crashes. If you see it that way, it's not too bad.
(Just sad that on my laptop I usually use only the CPU to save battery ;) )

Here is the whole test suite to reproduce the results:
