All, I found a few patterns that that will crash S3D for me every time without fail. Here is one of them.
Bring the included STL onto the build platform, click Mesh -> Separate connected surfaces, Then click Repair -> Identify Non-Manifold Edges
BOOM! This reliably causes the program to crash. I found two other patterns using different parts, However, if this pattern gets fixed, it may fix the other patterns as well. I suspect the BUG is a common routine used by multiple tools.
I hope this example actually helps get some stability back in the program. I'm afraid to do anything while is it printing because it has crashed so many times..
