You are 'stealing threads' (ask google, in case you don't know that term),
just so you know. However...

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>!
