title: What does the error "non-placement deallocation function"?
body: <p>I am getting the following error while compiling the serna-free package:</p>
  
  <pre><code>build/buildd-serna-free_4.3.0.20110221-2-i386-pAsDoD/serna-free-4.3.0.20110221/
    sfworks/common/RefCntStorage.h:76:10:
  error: non-placement deallocation function 'static void
  StringPrivate::RefCntData&lt;E&gt;::operator
  delete(void*,StringPrivate::size_type) [with E = QChar,

     sfworks/common/RefCntStorage.h:135:9:
  error: selected for placement delete
  </code></pre>
  
  <p>Code looks like:</p>
  
  <pre><code>void operator delete(void* p, size_type)
  {
      ::operator delete(p);
  }
  </code></pre>
