</div>You mean "copy or move constructor"; and you could use a test for the<br>
move-constructor case.<br></blockquote><div><br></div><div>Thanks for noting, I'll update the message and make the test cases more diverse.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">

There are corner cases such as<br>
<br>
C(const C&&);<br>
C(const C&, int i = 0);<br>
template<typename T> C(const T&);<br>
<br>
that would be interesting to test.<br></blockquote><div><br></div><div><div><font face="courier new, monospace">$ cat q.cc</font></div><div><font face="courier new, monospace">class A {</font></div><div><font face="courier new, monospace">public:</font></div>
