I have overloaded the new and delete operator, then I found this in the source code:<br><br>// note: this should really be a member of the load_ptr function<br>// below but some compilers still complain about this.<br>template&lt;class T&gt;<br>
struct heap_allocator<br>{<br>&nbsp; #if 0<br>&nbsp; // note: this fails on msvc 7.0 and gcc 3.2<br>&nbsp; template &lt;class U, U x&gt; struct test;<br>&nbsp; typedef char* yes;<br>&nbsp; typedef int* no;<br>&nbsp; template &lt;class U&gt;<br>&nbsp; yes has_op_new(U*, test&lt;void* (*)(std::size_t), &amp;U::operator new&gt;* = 0);<br>
&nbsp; no has_op_new(...);<br><br>&nbsp; template&lt;class U&gt;<br>&nbsp; T * new_operator(U);<br><br>&nbsp; T * new_operator(yes){<br>&nbsp; return (T::operator new)(sizeof(T));<br>&nbsp; }<br>&nbsp; T * new_operator(no){<br>&nbsp; return static_cast&lt;T *&gt;(operator new(sizeof(T)));<br>
&nbsp; }<br>&nbsp; static T * invoke(){<br>&nbsp; return new_operator(has_op_new(static_cast&lt;T *&gt;(NULL)));<br>&nbsp; }<br>&nbsp; #else<br>&nbsp; // while this doesn&#39;t handle operator new overload for class T<br>&nbsp; static T * invoke(){<br>&nbsp; return static_cast&lt;T *&gt;(operator new(sizeof(T)));<br>
&nbsp; }<br>&nbsp; #endif<br>};&nbsp;<br><br><br>If I am using a msvc that this does not fail on, is there anything wrong with implementing this code, or will I get a bunch of errors or &quot;hidden&quot; bugs? Also, are there any plans on implementing this in a future release(I am guessing it is a work in progress issue)?<br>
<br>Thanks in advance.<br><br><br>/Jacob Holm<br><br>
