Well - not what you asked - but you could reduce the polygons by a factor of 2X or 100X potentially without any reduction in resolution (resolution after printed). I love using meshlab:
Click on menu item: "filters" "remeshing..." "quadratic edge collapse decimation". I set quality to 1 as recommended in a shapeways article about this subject.
I had a model of a human with over 10 million polygons but I wanted to print it only .5 inches high. I reduced the polygon count to 10K polygons and it was still more than I needed. After reduction Cura handled it nicely (before reduction Cura had issues).
Most likely it's a memory related issue, the released version abuses memory a bit. Can you see if the version from the new support material test also gives you this problem with the same models&settings?

We don't often release an alpha version of Ultimaker Cura... So what's different this time? This Alpha contains such a huge slicing engine overhaul that we really need your help!
We wish to celebrate and honor the innovators that push forward the field, technology and world. We opted to not present it as a competition or ranked list. Every innovator has earned his spot on that list in their own way. We also look at the 3D printing industry as a whole and not limit the list to those only using Ultimaker.
