    <h1>Known Problems and Workarounds</h1>

This is a list of known problems compiling the BGL for different compilers and
versions.

<ol>
  <li>The <code>subgraph</code> adaptor has several known problems:
    <ul>
      <li>Each instance of subgraph has its own copy of internal
      vertex and edge properties. Only at the root subgraph are the
      properties valid. </li>

      <li>Edge and vertex removal functions are unimplemented.</li>

      <li>The graph is required to have vertex descriptors of integral
      type (that are the same as the vertex index). Practically
      speaking, that means subgraph only applies to adjacency lists
      with <code>VertexListS</code> = <code>vecS</code>.</li>
    </ul></li>

  <li>The <code>EdgeListS</code> parameter to the adjacency list is
  essentially fixed to <code>listS</code>: other selectors are
  unlikely to work.</li>

  <li>Using a GraphProperty with adjacency_list may cause a VC++ internal compiler error.</li>
  <li>Using get(property, graph, edge) may cause a VC++ internal compiler error.</li>
  <li>&quot;using boost::tie;&quot; may cause VC++ internal compiler error.
</ol>
