Compiler warning with counting_iterator in MSVC

[mfrancis95]

My code:
thrust::counting_iterator<unsigned> countingIterator(0);

The warning:

note: see reference to class template instantiation 'thrust::counting_iterator<unsigned int,thrust::use_default,thrust::use_default,thrust::use_default>' being compiled

And here's a deeper trace of it:
