We suppose that Window 10 works incorrectly with "Large Pages" at:
- Windows 10 1703 (15063)
- Windows 10 1709 (16299)
- Windows 10 1809 (17763) on some CPUs that have no 1 GB page support.
We need more information about that new BUG in Windows.
- Windows 10 1703 (15063) : incorrect allocating after VirtualFree()
- Windows 10 1709 (16299) : incorrect allocating after VirtualFree()
- Windows 10 1809 (17763) : the failures for blocks of 1 GiB and larger,
if CPU doesn't support 1 GB pages.
Windows 10 1903 (18362) probably works correctly.
