Every stack trace through that file now carries different line numbers, so a tracker that hashes the trace files a bug it has seen a hundred times as a brand-new issue. Meanwhile an older issue titled <code>TimeoutError</code> has collected comments from people who each fixed a different timeout and wondered why it never closed.</p> <p>Grouping fails in both directions at once. One bug turns into hundreds of issues because the message embeds an order ID, the line numbers moved, or a framework upgrade changed the frames in the middle. Two bugs turn into one because every timeout in the codebase raises the same exception type from the same retry helper.</p>
