Manually clearing the global device vector

Browse Source 
The vector of devices is a global object, which destruction order is
undefined. In some platforms, the OpenCL library has been unloaded
before this destructor is hit, which causes a segmentation fault after
the program ends.  By clearing the global vector of devices on
destruction of the OpenCL and SYCL Stream benchmarks we avoid the
problem.
