I think the problem is that macros doesn't work the way as you think they 
do. In fact your first declaration of set1() never gets called.

What you assume is: set1() is immediately replaced by the content of the 
last definiton of that macro.
But: In fact this is only done later, when the macro containing the call 
to set1() is called... but at this time you already redefined set1()

This means: your scene is equivalent to

#macro set2()	set1() #end
#macro set1() set2() #end
set1()

-> infinite recursion.
