My suggestion:
<Type Name="boost::container::deque&lt;*&gt;">
    <Variable Name="bufferSize">sizeof($T1) &lt; 512 ? size_t(512 / sizeof($T1)) : size_t(1)</Variable>
    <Variable Name="size">$bufferSize *
        (members_.m_finish.m_node - members_.m_start.m_node - 1) + (members_.m_finish.m_cur - members_.m_finish.m_first) +
        (members_.m_start.m_last - members_.m_start.m_cur)</Variable>
