I have already sent the source of a LuxRender OpenCL kernel that wasn't 
possible to compile with 24GB of ram. The problem was very easy to 
reproduce: loading the kernel inside AMD KernelAnalyzer2 was enough to 
trigger an out of memory on Linux and a compiler internal error on Windows.

According our contact inside AMD, this problem has been fixed. The fix 
should be available with one of the next release of Catalyst drivers.

May be this fix will solve the Cycles related problem too.
