Standard Library</h2> <h3>[delete-const-pointer] Deleting <code>const X *</code> does not work</h3>
Trying to delete a pointer to a cv-qualified type gives an error:
<pre>
void f()
{
const int *p = new int(5);
delete p; // C2664: cannot convert from "const int *" to "void *"
}
</pre>
<strong>Workaround:</strong> Define the function
<pre>
inline void operator delete(const void *p) throw()
{ operator delete(const_cast&lt;void*>(p)); }
</pre>
and similar functions for the other cv-qualifier combinations, for
operator delete[], and for the <code>std::nothrow</code> variants.
