Hello,
I want to check my program for memory leaks (which may feel comfortable in cuda driver 
).
However when executing I get this warning:

Does cl::Program contain memory objects?
If yes: Where and how can I split this relationship?
I also observed that this warning vanishes when I omit the corresponding enqueueNDRangeKernel.
Any hints?
best regards,
