I get strange error messages running the following code in POV-Ray 3.6 
(It works fine in 3.5):

<POV>
#declare MyF = 	function { 1 }

#macro Test(F)
	(1)
#end

#local a = 0;
#while (a<20000)
   		
	#debug "Works\n"
	#local Dummy = Test(MyF);  			
   		
	#local a=a+1;
#end
</POV>



Here's the output:

<output>
...

File: bugsearch.pov  Line: 13
File Context (5 lines):

#local Dummy = Test(MyF)
Parse Error: Identifier expected, incomplete function call or spline 
call found
  instead.
</output>


As you can see, it outputs "Works" more than 50 times (did not copy all 
of it :) before raising the error. I don't understand this, as each time 
absolutely the same code is executed (content of identifiers are 
unchanged etc.).

If I use

	#local Dummy = Test(function { MyF(x,y,z) });  			

(i.e. wrapping the function in another function block), it works again.

I'm experiencing this on Gentoo 2004.0, with 1 GB Ram and POV 3.6 
official binaries. As I said before, it works without problems under POV 
3.5.

Can anyone confirm this behaviour?
