Using Inspector 2016 on Windows I can see there are uniniatialized reads dsyrk occasionally. When I replace the syrk call by the equivalent loops then it goes away.
To be fair in both cases the results are the same but I am worried anyway.
I am fully aware I do not have a proof of an issue yet. However, are you interested in a small example? Or is it well know that Inspector produces false results on MKL. I think you claim valgrind cannot be trusted.
Thanks in advance.
