The following pipeline fails, as expected, with err:XS0026 :

  <p:pipeline xmlns:p="http://www.w3.org/ns/xproc"> 
   <p:filter>
    <p:with-option name="select" select="$notBound">
     <p:empty/>
    </p:with-option>
   </p:filter>
  </p:pipeline>

But the following pipeline produces a segfault (in Calabash 0.9.9):

  <p:pipeline xmlns:p="http://www.w3.org/ns/xproc"> 
   <p:option name="notBound"/>
   <p:filter>
    <p:with-option name="select" select="$notBound">
     <p:empty/>
    </p:with-option>
   </p:filter>
  </p:pipeline>

with the following stack trace:
