 *** recommendation #1 ***

 1. Found recursive call at:
   stack: large_name_to_force_line_break_in_stack_msg :: make-wrapper.c:14 <-
          large_name_to_force_line_break_in_stack_msg :: make-wrapper.c:18 <-
          rec :: make-wrapper.c:23 <-
          main
-
 Consider patching, stubbing or adding an ACSL specification to the recursive call, then re-run the analysis.

 *** recommendation #2 ***
 2. Found function with missing spec: large_name_to_force_line_break_in_stack_msg
    Looking for files defining it...
