Error while exiting program on VS2013

Getting an error while exiting an app with sample code in SimpleDepthViewer-SFML. Everything else works as it should.
_BLOCK_TYPE_IS_VALID(pHead->nBlockUse)

Thanks for the report. We’ve logged this in our bug tracker. For now, this is a relatively harmless bug and if you compile and run in Release mode, the debug assertions will not fire.

Actually I was already on Release Mode. I thought the libraries were not Debug or Release specific.
