crash with snapshot & 1.5.1 when smoothing

[Stem]

There is a memory limit cor the 32bits application - I think you know about.
Wings3d can reach it easy if you smooth so many times an object.

Smoothing(sub-d) a cube 5 times should not be hitting memory limit. If it was, then there is a serious issue with wings, as 5 levels of smoothing on a cube is only creating 6144 polygons, and actually using (in 1.4.1) 84mb of memory.

Werl.exe and erl.exe are, by default, LAA (Large Address Aware), so even at 32bit, they can use(if available) approx 3.5GB of memory.
Having a quick check of the OP crash, I see the same crash, but certainly not a problem due to lack of memory.

I have seen many crashes in a few hours of use with the new 1.5.1 version (both 32bit and 64bit), but the crash(s) are unpredictable and unrepeatable (apart from the one mentioned by OP), and there is no dump created(just the windows error popup forcing the close of erl.exe), so no way to accurately report a bug.
