Open the file, then press shift-z to render using pro render. Then change the max displacement value to for example "20". dies every time for me.

This is repeatable. But, the plugins crashes semi-randomly in regular usage as well and is harder to report. 1.7 is very unstable for me on MBP15 (2017) with pro 560 as well as with attached vega 64 in razer Core X.(single and dual) mac os 10.13.6 official, blender 2.79b

Hey Filip.  I tried with the same MBP and couldn't reproduce this crash after many renders....

[gelert]

I crashed on my MBP with no eGPUs - I couldn't even get to change a value... it crashed as I moved to it into the nodes!

And also crashes on the eGPUs only as well. (Previous test was dGPU on the MBP2017)

I don't get the chance to change a value.

The preview renders great and I can move about.

Go anywhere near displacement Max / Min and BOOM. Blender is out of there.

Viewport rendering works, but looks odd. (see screenshot)

Render image -> Blender crashes

Changing displacement value to 20 -> Blender crashes

iMac pro with Vega64; ProRender 1.7.203; Blender 2.79

[voidcore]

This still crashes for me in 1.7.1.212 on Mac.

Hey Filip.  Can you try this with the weekly beta builds out now?

I can't reproduce this issue there.

[voidcore]

A lot better! It doesn't crash at once and I could test it a few minutes, changing parameters etc. Then it locked up with all cores on the CPU maxing out an I had to force quite Blender after a few additional minutes of waitning. (this was using 1.7.231 and a eGPU btw)

I could repeat this behaviour by adding an object using the same material (and setting the subdivision parameters to the same as it was for the other object since those parameters  doesnt seem to follow with the material) and switching forth and back from interactive viewport rendering (shift-z)

Here is the tail of the last log before I killed the process:
