https://svn.boost.org/trac10/ticket/5686 <p> The current implementation of shared_ptr doesn't overload operator-&gt;*, so member function and member variable pointers don't play nicely with shared_ptrs. I would imagine that this is trivial to fix given the existing operator-&gt; implementation. Here's an example of what doesn't work but should: </p> <div class="wiki-code"><div class="code"><pre><span class="k">class</span> <span class="nc">A</span> <span class="p">{</span> <span class="k">public</span><span class="o">:</span> <span class="kt">int</span> <span class="n">memberA</span><span class="p">;</span> <span class="p">}</span> <span class="p">...</span> <span class="kt">int</span> <span class="n">A</span><span class="o">::*</span><span class="n">memberVariablePtr</span> <span class="o">=</span> <span class="o">&amp;</span><span class="n">A</span><span class="o">::</span><span class="n">memberA</span><span class="p">;</span> <span class="n">shared_ptr</span><span class="o">&lt;</span><span class="n">A</span><span class="o">&gt;</span> <span class="n">ASharedPtr</span><span class="p">(</span> <span class="p">...</span> <span class="p">);</span> <span class="c1">// The following two pieces of code should be functionally identical</span> <span class="c1">// 1) Doesn&#39;t compile.
