Taxying for a 07R departure from northside terminals at Barcelona you taxy right behind the 07L threshold and 25R localiser.
But you do not cross the paved surface of 07L. The threshold is displaced a considerable distance which would allow landing over taxying aircraft. Not what the OP is suggesting.
Here at CYYZ landing on 33L is permitted while taxying on D to 06L and landing on 33R is permitted when there are vehicles (usually snow removal vehicles, but not aircraft) on 06L. Taxying aircraft are held clear of the 33R approach and must be clear of the area by the time landing traffic is 1nm from touchdown. Not discretionary like in the Frankfurt example above.
