System Information
Win10 1703 x64
GTX 780 3GB

Blender Version
Broken: Latest Buildbot builds and own builds
Worked: Official 2.78c

Short description of error
Blender instantly closes / crashes when plugging a texture (in my case a 16-bit / 8k PNG, but it also crashes with tiny 8-bit JPEGs etc.) into the Displacement output port of a material but only if the "Displacement Method" is "True" or "Both". The strange thing is that in "Supported" mode you don't have access to this option (default is "Bump" I guess) and Blender doesn't crash.
But if you switch to "Experimental", set the "Displacement Method" to something other than "Bump" and then switch back to "Supported" mode (where this option shouldn't have any effect at all) as soon as you connect any image texture to the Displacement output Blender crashes.
Official 2.78c and older Buildbot builds don't crash. I can't tell when it started to crash but it must be since a few days ago.crash_v04.blend

Exact steps for others to reproduce the error

Open the attached blend file
Connect the image texture to the Displacement output port in the node editor
Crash
