	//	There is currently a codegen bug in the X360 compiler, for which the below CFmtStr initialization is a workaround.
	//	  The problem appears to be that the stackallocs below cause 'eRenderPath' (when pushed onto the stack) to be
	//	corrupted to some value which is less than zero. Replacing the stackallocs with regular mallocs, or adding any
	//	additional code (e.g. this CFmtStr) which references the 'bShadowDepth' variable will cause the bug to disappear.
	//	  The original symptom was a GPU HANG on starting a Co-op game; bShadowDepth was erroneously determined to be
	//	FALSE during the shadow depth pass, so models were rendered using their regular (rather than NULL) pixel shaders,
	//	at a time when the pixel shader GPR allocation is set to its minimum value of 16.
