[CrashReport] UE4Editor_CoreUObject!FLinkerSave::FLinkerSave() [linkersave.cpp:31]

This is a longstanding and common crash that has occurred since at least the 4.11 release. The error appears to occur while trying to access a .tmp file.

User Descriptions

• I left unreal unattended for an hour or so and it crashed
• Imported an FBX file from 3ds max and put the FBX file in the scene. It crashed about three minutes later
• I was simply importing a NASA file for the MMSEV a space rover obj file.
• I'm also running Maya 2015, as I'm having to retry a particular FBX import a couple of times to try to get the textures transfer. I also have a couple of reasonably high poly meshes in my level, but nothing too much. I have an ocean surface running. This is the second crash today; I should probably just close Maya.

• Try to save something in the editor with a path that's close to the maximum length on Windows (260 characters). Example from one crash report: love-lips-sponge-face-girl-girl-gifts-heart-heart-heart-valentine-holiday-textures-vector-pictures-wallpapers-desktop-wallpaper-best-wallpapers-desktop-wallpaper-shirokoformat_Auto.uasset (don't ask me)
• While saving, the editor appends a 32 character GUID to the asset name and stores it in the project's saved folder. Editor crashes if the total length of that path is > 260 characters.
