This is one of the "typical" NURBS or mesh failures.

This one appears to be in the same category as these ones:

The sad (or very interesting) part is that this model works in this version https://github.com/ruevs/solvespace/releases/tag/WindowsXPPost3.1
Perhaps it is the same type of failure as "wrong3" #683 (comment) that only fails in some builds probably based on whether double is 64bit IEEE or 80bit Intel FPU.
