title: windows application crashing with pure virtual function call
body: <p>I have a Windows application, it crashes every now and then and not reroducibly.
  When it does, I get pure virtual function called. I have set it up to create a Windows dump using ADplus and even when it crashes, there is never a dump.</p>
  
  <p>I am pretty sure this is build error, I am building using VC2008 SP1 and this is the release build.</p>
  
  <p>Any insights on this? How can I debug this, it is a release build with .pdb file and map file.</p>
  
  <p>Thanks
  Reza</p>
