<p>I am programmatically creating PDFs, and a recent change to my generator is creating documents that crash both Mac Preview and Adobe Reader on my Mac.  Before Adobe Reader crashes, it reports:</p>

<blockquote>
  <p>There was an error processing a page.
  There was a problem reading this document (18).</p>
</blockquote>

<p>I suspect that that "18" might give me some information on what is wrong with the PDF I've created.  Is there a document explaining the meaning of these status codes?</p>
