Perhaps, only the pre-processor would be in a feedback loop with the early parts stages of the program life-cycle. Typically the linker and pre-processor are one way operations. In a developing organism, the environment feeds back on the cells developing and triggers new responses which causes new environmental changes which causes new feedback.
Biology is full of bizarre examples of when this process goes awry and our bodies have bizarre features. Dawkins's example of the Laryngeal nerve that makes a crazy loop down into the mammalian chest cavity is the classic example.
