What is the ruling regarding a wall that is cracked but not leaning?

Primary text

If the wall does not belong to the demanding party but is cracked, and collapse is not feared because the cracks run lengthwise (*bi-tul*), its ruling is identical to that of a sound wall; demolition is not required because there is no fear of collapse, thus resembling a sound structure. If collapse is feared, such as when the cracks run crosswise (*bi-al-'ard*), its ruling is that of a leaning wall because there is fear of destruction, thus resembling the leaning structure.
