System Information
Windows 7, nvidia quadro 1000m

Blender Version
Broken: 2.78 RC 0e5089c (using experimental feature set)
Worked: N/A

Short description of error

While using adaptive subdivision and an image texture node as a displacement map, blender sporadically crashes on this mesh. It doesn't render displacement if it does render, but shows that it's tessellating in render building information. It is generally prone to crashing when working with this mesh (fairly simple mesh) and doesn't displace like other meshes are able to.

Exact steps for others to reproduce the error

open the attached blend file

micro displacement bug .blend

try to render, plug and unplug image texture nodes, flip to the material button and back again, etc.
adaptive subdivision/displacement doesn't work as it does with other meshes if it is able to render without crashing, and blender is generally prone to crashing while operating with this mesh/material

This is a great feature everyone, it works really well in so many cases (with the exception of dupliverted objects and particles). AMAZING. Thank you all so much for all the hard work and incredible things you put into blender! I wish this was a more definitively reproducible bug but it seems to happen at different times, never renders right for me though.

Apologies for the large file size but I included an EXR that I used previously with displace modifier and multiresolution, as well as a PNG (in case the EXR happened to be what was causing the problem).

Thanks in advance for any help, and thank you for all you guys do.

Thank you very much Brecht! Downloaded a daily build and it's working wonderfully. I'm so excited!! :D Sorry for bumping but wanted to say thanks for directing me to the fix and duplicate, and general thanks to devs for all their work on such amazing software.
