Commenting out the latter fixes the issue BTW (there are quite a few traits class specialisations that need to be commented out though!). </p> <p> Not sure if this is a general STLPort issue (don't see why it should be), or a specific compiler issue. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/6462 Trac 1.4.3 John Maddock Sun, 29 Jan 2012 17:57:19 GMT https://svn.boost.org/trac10/ticket/6462#comment:1 https://svn.boost.org/trac10/ticket/6462#comment:1 <ul> <li><strong>owner</strong> changed from <span class="trac-author">nasonov</span> to <span class="trac-author">Antony Polukhin</span> </li> </ul> Ticket Antony Polukhin Wed, 01 Feb 2012 04:28:28 GMT https://svn.boost.org/trac10/ticket/6462#comment:6 https://svn.boost.org/trac10/ticket/6462#comment:6 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> <p> Merged to release in <a class="changeset" href="https://svn.boost.org/trac10/changeset/76887" title="Merge from trunk (fixed #6251, fixed #6453, disabled some ...">r76887</a> </p> Ticket
