microsoft/STL#3824 microsoft/STL#4000 microsoft/STL#4339 Add escape hatch due to STL change resulting in issues with binary compatibility. https://github.com/microsoft/STL/wiki/Changelog "Fixed bugs: Fixed mutex's constructor to be constexpr. #3824 #4000 #4339 Note: Programs that aren't following the documented restrictions on binary compatibility may encounter null dereferences in mutex machinery. You must follow this rule: When you mix binaries built by different supported versions of the toolset, the Redistributable version must be at least as new as the latest toolset used by any app component. You can define _DISABLE_CONSTEXPR_MUTEX_CONSTRUCTOR as an escape hatch."

_ENABLE_CONSTEXPR_MUTEX_CONSTRUCTOR, instead of opt-out via_DISABLE_CONSTEXPR_MUTEX_CONSTRUCTOR. This avoids potential breakage until we can update the VCLibs UWP framework libraries. Doing so in time for 17.8 is probably impossible at this late stage; we'll get this straightened out and enabled by default for 17.9.
