<p>Thank you, David. By looking at the tracings in the log file I was able to figure out where the trouble lies. Just in case someone googles this, I was getting into trouble writing </p>
<p><br>
</p>
<p> \Numberstring{chapter}</p>
<p><br>
</p>
<p>to the answer file. (The \Numberstring{..} command is from the fmtcount package and for example if the counter is 3 then it returns "Three".) I appreciate the help.</p>

last point before the error, you should see macros expanding and<br>
almost certainly getting in a loop somewere<br>

shows instead a "59i" used on the stack, so I think there is something wrong in that particular answer. But that answer has no recursion, just text.<br>
