Description

This recent news about a data corruption bug in some versions of Windows 10's Large Page support is very interesting.
I recommend Bohemia Interactive to actively follow how this unfolds and possibly disable use of Large-Pages on some versions of Windows 10.

Additional Information

QUOTE VapourSynth - http://www.vapoursynth.com/

A Windows bug exists where a VirtualAlloc call immediately after VirtualFree
yields a page that has not been zeroed. The returned page is asynchronously
zeroed a few milliseconds later, resulting in memory corruption. The same bug
allows VirtualFree to return before the page has been unmapped.
