I'm getting memory leaks when deserializing objects and I can't figure out what I'm doing wrong. I'm using VC++ 2005. I've boiled it down to the following code:
//virtual ~Base() { } // uncommmenting this causes leaks to disappear
The base class needs a virtual destructor, thus uncommenting this is needed.
I solved my problem seconds before I got your message :). I had
actually done that in what I thought was the class giving issue but it
turns out I had several base classes that were missing virtual
destructors so that fix didn't appear to work because I was still
getting tons of leaks.
I am curious, though, about why the leaks only happened in when I
deserialized and not in any of the other instances I created myself. Does
shared_ptr perform some kind of trickery to detect the type to delete through, even when the shared_ptr is typed for the base class?
