https://svn.boost.org/trac10/ticket/11528 <p> The attached test program compiled with MSVS 2013, but doesn't with MSVS2015 in debug mode and Boost-trunk as of 2015-08-05. The <code>transform_iterator</code> is recognised as Boost foward iterator, but only as STL input iterator because its reference type is <code>int</code>. Since <code>boost::max_element</code> uses <code>std::max_element</code>, it doesn't compile in debug mode with: </p> <pre class="wiki">c:\program files (x86)\microsoft visual studio 14.0\vc\include\xutility(1005): error C2338: next requires forward iterator </pre><p> I'd be happy if this code compiled and worked, or if otherwise the Boost assertion would fire because the transform iterator is not a Boost forward traversal iterator. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/11528 Trac 1.4.3 Dennis Schneider <dsr@…> Thu, 06 Aug 2015 14:16:46 GMT https://svn.boost.org/trac10/ticket/11528 https://svn.boost.org/trac10/ticket/11528 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">test.cpp</span> </li> </ul> <p> Code in question </p> Ticket Dennis Schneider <dsr@…> Thu, 06 Aug 2015 14:17:04 GMT https://svn.boost.org/trac10/ticket/11528 https://svn.boost.org/trac10/ticket/11528 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">test-compile.txt</span> </li> </ul> <p> Compiler output </p> Ticket Michel Morin Thu, 20 Aug 2015 11:14:51 GMT
