Hello, why is not possible to call this: -- cut here -- #include class Trida; boost::shared_ptr<Trida> trida; class Trida : public boost::enable_shared_from_this<Trida> { public: Trida() { trida = this->shared_from_this(); }; }; int main() { boost::shared_ptr<Trida> tr(new Trida()); return 0; } -- cut here -- It throws in constructor of shared_count(weak_count const & r). I think the problem is that there is no one shared_ptr instance that owns object tr yet when calling constructor. May be it is BUG (and I don't know how to handle that). Can be at least note in documentation? -- Petr "Fers" Ferschmann -=[ petr@ferschmann.cz ]==[ http://petr.ferschmann.cz/ ]=- -=[ Koukni na http://www.postcard.cz/ ]==[ +420 604/781 009 ]=- GPG Fingerprint: [83B0 6378 7A9D D993 035E 60BD FEEC F665 D2C8 1B9A] [Non-text portions of this message have been removed]
