In the inc.fail the program generates tables  but no information is called from them that is they are not used at all.
I can not understand why they apear.
In this version  CVAVR  1.25.8 in ......project_file.inc besides definition of registers where the compilator writes bit variables, global variables,  HEAP START MARKER INITIALIZATION and so on, he generates these tables also.

If LIC is not correct CVAVR generate error.
