[reSIProcate] VS2005 crashing with DUM

[Byron Campen]

	I'm not willing to buy this without some hard evidence. I have never  
had a problem with auto_ptr and virtual d'tors, and a Google search  
turns up nothing. Additionally, I can't think of a plausible reason  
why this would be the case (auto_ptr<Foo> isn't going to be calling  
~Foo() directly).

Best regards,
Byron Campen
