You are 'stealing threads' (ask google, in case you don't know that term), just so you know. However... On Saturday 04 December 2004 17:59, Oliver Kullmann wrote:

I seriously doubt that you used the same compiler. Above warning suggests that you used an older version of the stdlib (and compiler), which can lead to all kinds of subtle problems. Recompile that lib first and try again. About the problem of not having a virtual dtor: it is not necessary. The general rule is to have either a public virtual one or a non-public non-virtual one. No, I did not inspect the code in question, so won't comment on that. Another thing is that when using shared_ptr<>, they still manage to call the right dtor, you can even store objects safely in a shared_ptr<void>! Uli
