Description

I occasionally get a 'double free or corruption' error with the OCL_ML/Kmeans test. To reproduce, run:

./opencv_test_ocl --gtest_filter='*Kmeans*'

This error doesn't happen every time, but you can see the memory errors in valgrind.

It seems like the root of the problem is the destructor for the static object:

static __Module __module; from cl_context.cpp

tries to destroy ContextImpl* ContextImpl::currentContext which is also static and may have been deleted already by a static destructor.

Hi Tom,
All test images are located in additional repo https://github.com/Itseez/opencv_extra
