Short description of error
ANT eroder (vertex weight tool) + adaptive subdivision causes crash or freeze when rendering

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

1-Create a landscape with the new ANT landscape tool (huge improvement, thx). Give it a material with true subdivision. Add subdiv modifier with adaptive subdivision
2- Preview it in cycles ----> everything is OK

NOW
3-Go to weight paint mode. Weights>Landscape eroder. Vertex groups are added based on geometry
4-Retry preview in cycles : Crash or freeze during Tesselation operation (denser meshes tend to crash)

hi, provided file indeed crashes, opened file, pressed render, stalled my entire computer, requiring manual shutdown of computer. literally locked up my whole system, no mouse, no keyboard.
don't try this with works in progress.
