title: python connecting to Oracle using pyodbc sometimes kills python interpreter
body: <p>Periodically when using pyodbc to create a connection to an oracle database, it kills the interpreter.</p>
  
  <pre><code>import pyodbc
  connectString = 'Driver={Microdsoft ODBC for Oracle};Server=&lt;host&gt;:&lt;port&gt;/&lt;db&gt;.&lt;host&gt;;uid=&lt;username&gt;;pwd=&lt;password&gt;'
  cnxn = pyodbc.connect(connectString)
  </code></pre>
  
  <p>Say 1/5 of the time this will just drop me from the Python prompt (>>>) down to my dos prompt (C:)</p>
  
  <p>Any ideas of why this happens or how to fix it?</p>
