crash with snapshot & 1.5.1 when smoothing

[micheus]

I do this sometimes to figure out what the smoothed objects looks like and then go back to the original object I'm working on.

by using the opencl option instead of truely smooth the object should work better for this case.
Just to know, how many memory your system has?
With the last snapshot I could smooth 9x until call smooth preview and crash ere.exe. But, I started with only 1.4GB used by other process and then it tried to break my 4GB limit and stoped to response when erl.exe was using 2.7GB.
