https://svn.boost.org/trac10/ticket/10707 <p> Subgraph copy constructor doesn't copy all the data required for normal working in case of the subgraph object actually represents children subgraph. As a result, copied object is not equal to original one and usually can't be used any more. </p> <p> Here's the data fields that aren't copied: </p> <ol><li>m_graph (is copied only in case the subgraph object represents root subgraph). </li><li>m_local_vertex and m_local_edge containers (ok for root subgraph, data loss for children subgraphs). </li></ol><p> The patch with fix is attached. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/10707 Trac 1.4.3 4ernov@… Tue, 28 Oct 2014 17:38:18 GMT https://svn.boost.org/trac10/ticket/10707 https://svn.boost.org/trac10/ticket/10707 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">fix_copy_ctr.patch</span> </li> </ul> Ticket Alexey Chernov <4ernov@…> Tue, 28 Oct 2014 17:47:35 GMT https://svn.boost.org/trac10/ticket/10707#comment:1 https://svn.boost.org/trac10/ticket/10707#comment:1 <ul> <li><strong>keywords</strong> subgraph added </li> </ul> Ticket
