Can't reproduce, the test works for me:

$ ./quicksort  1 16 16

This is with Intel Skylake GPU:

  Platform Name                                   Intel(R) OpenCL HD Graphics
Number of devices                                 1
  Device Name                                     Intel(R) Graphics [0x1912]
  Device Vendor                                   Intel(R) Corporation
  Device Vendor ID                                0x8086
  Device Version                                  OpenCL 3.0 NEO 
  Driver Version                                  20.51.18762
  Device OpenCL C Version                         OpenCL C 3.0

Which hardware do you use, is it CPU or GPU ? and which driver version ? It seems your driver has a problem with the generated SPIR-V.

It is a Gen8 GPU:
