<p>A link stack in a processor is repaired in response to a procedure return address misprediction error. In one example, a link stack for use in a processor is repaired by detecting an error in a procedure return address value retrieved from the link stack and skipping a procedure return address value currently queued for retrieval from the link stack responsive to detecting the error. In one or more embodiments, a link stack circuit comprises a link stack and a link stack pointer. The link stack is configured to store a plurality of procedure return address values. The link stack pointer is configured to skip a procedure return address value currently queued for retrieval from the link stack responsive to an error detected in a procedure return address value previously retrieved from the link stack.</p>
