I built Unreal Engine from master, commit https://github.com/EpicGames/UnrealEngine/commit/89aee9dfa9a8d250d5b0851fb059858b325407ed with VS2015 on Windows 10.
I can launch Engine\Binaries\Win64\UE4Editor.exe and create a new FPS or Flying project, but opening the new project always results in a crash within a few seconds.
Debugging with
"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe" /debugexe Engine\Binaries\Win64\UE4Editor.exe "C:\Users\unreal\Documents\Unreal Projects\MyProject2\MyProject2.uproject"
shows
with this stack trace (also pastebined here):

I am using the latest NVIDIA drivers (355.82) and I am not running out of memory.
I see a nearly-identical stack trace if it is built with VS2013 instead:
Anything I should try? Thanks a lot.
