LuxRender crash with Cloud volume region

[cwichura]

I am using the most current weekly build on Windows 7 64-bit. I am attempting to add a cloud volume region to a scene file, and it is causing LuxRender to crash during scene file parse. The crash is a heap corruption exception. If I comment out the cloud volume, Lux starts without issue.

I am using path with maxdepth 32. The cloud is specified using the values found in the original Cloud discussion thread:

I realize this is an old volume, but I'm hoping it is still supported. At the very least, it shouldn't cause LuxRender to crash.

Thanks
