crash with snapshot & 1.5.1 when smoothing

[ggaliens]

What are the SYMPOTMS of the BUG that was fixed ?

I was using last months 64 bit release and for first time in a while ... I got a crash that looked like it happened at some Driver or NVIDIA level as per message that popped up at me. Maybe I should try to snaphot the message ... even if Dan's fix does not apply.

I'll probably just go ahead and upgrade again anyways.

I had like 1.5 million count of some edge,face or vertex. Don't recall which.
And usually I can smooth. But last night ... BAM ! Probablly faces in mesh we
a bit more twisted or sliver or degenerate in shape as compared to prior smooths
of same magnitude and prob same 64bit release.
