FumeFX Crash on Render

[Eric-S]

We've hit a render crash that seems to be related to multiscattering. i.e. if its 'on' it will crash *certain frames* on *certain fumeboxes*. But not all.
But crashes the same frames every time if its occuring (on multiple machines). Uncheck multiscatter and no crash.

I wonder if its the same issue? I never saw this with version 1.0 of fumefx (over years of use).
But I can repro in 2.1a in both max 2009 and 2011 with the same scene.
Seems to be a fairly common occurrance as multiple users here have had this issue with completely unique fx (i.e. All built from scratch-not shared)

Any chance this crash bug is related?
