https://svn.boost.org/trac10/ticket/4717 <p> In boost/function/function_template.hpp, there is a local static object stored_vtable which is initialized statically. Since this variable is not const, it is placed in writable memory (or section). </p> <p> This can be a critical problem on some embedded, ROM environment which has only XX KB of RAM. The variable is small, but instanciated for each combination of template arguments. </p> <p> Digging the history, this variable was const in old versions, but was changed to non-const in <a class="changeset" href="https://svn.boost.org/trac10/changeset/43884" title="Change Boost.Function allocator behavior, from Emil Dotchevski">r43884</a> (accidentally, I think). After that, some changes in <a class="changeset" href="https://svn.boost.org/trac10/changeset/43884" title="Change Boost.Function allocator behavior, from Emil Dotchevski">r43884</a> were reverted in <a class="changeset" href="https://svn.boost.org/trac10/changeset/49326" title="Fix Boost.Function thread safety issue again">r49326</a>, but the constness was left as non-const. I believe that this was just an oversight. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/4717 Trac 1.4.3 Kazutoshi Satoda <k_satoda@…> Wed, 06 Oct 2010 22:48:04 GMT https://svn.boost.org/trac10/ticket/4717#comment:1 https://svn.boost.org/trac10/ticket/4717#comment:1 <ul> <li><strong>type</strong> <span class="trac-field-old">Patches</span> → <span class="trac-field-new">Bugs</span> </li> </ul> Ticket Daniel Walker Thu, 11 Nov 2010 19:12:59 GMT https://svn.boost.org/trac10/ticket/4717 https://svn.boost.org/trac10/ticket/4717 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">djw_function_const_vtable.patch</span> </li> </ul> <p> Implements a const stored_vtable.
