In test:

But the bug is on 6th line, not the 4th line.

In a simpler test:

 (defun test (v)
   (or (= (length v 0))
       (= (length v) 1)))

produces

 test.el:2:8:Warning: `=' called with 1 arg, but requires 2
 test.el:3:11:Warning: `length' called with 2 args, but requires 1

but after changing the second `length'

 (defun test (v)
   (or (= (length v 0))
       (= (safe-length v) 1)))

the error output is correct:

 test.el:2:8:Warning: `=' called with 1 arg, but requires 2
 test.el:2:11:Warning: `length' called with 2 args, but requires 1
