Created an attachment (id=403148)
 --> (http://bugzilla.novell.com/attachment.cgi?id=403148)
File containing the LINQ query

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/534.7

When trying to compile the LINQRaytracer sample of the Parallel Extensions
Samples suite with xbuild, dmcs fails to compile the Raytracer LINQ query
whereas it used to work previously.

The relevant error from log is reproduced below:

LINQRayTracer.cs(84,66): error CS0103: The name `pos' does not exist in the
current context

But it seems pos is correctly defined with a let clause earlier in the LINQ
query.

The project can be downloaded from here:
http://code.msdn.microsoft.com/ParExtSamples 

I'm also attaching LINQRayTracer.cs file just in case.

Reproducible: Always
