Just discovered that the following also produces the error and fails-- unless
the #debug is there. Seems that in this case, the inner #end actually *needs*
something to follow it! I tried adding #break and/or #end here and there
(guesswork!) to try and MAKE it work without the #debug, but no luck so far.

#declare R = seed(4711);
#for (I, 1, 100)
  #if (rand(R) < 1.1) // always less than 1.1
     #break // terminate loop early
  #else
  #end
  // #debug concat(str(I,0,0), " iterations and counting\n")
#end
