我使用Boost 1.39。我已經使用boost::flyweight<no_locking, hashed_factory<> >
實現了我的類(我的應用程序是單線程的)。我的課測試程序通過罰款,但是當我在應用程序中使用,我在增加flyweight恐慌
#9 0x08de7c3e in boost::flyweights::detail::refcounted_value<boost::flyweights::detail::default_value_policy<SharedFileAttr>::rep_type, SharedFileAttr>::release (this=0x0) at /usr/include/boost/flyweight/refcounted.hpp:89

at /usr/include/boost/flyweight/flyweight.hpp:196
通知恐慌,在幀#9,這是爲0x0
我不知道這怎麼可能從我的代碼使用boost :: flyweight來引起引用計數問題。畢竟,我的界面只包含添加flyweight對象的方法,並銷燬它們。
我不知道如何解決問題。有任何想法嗎?
我們可能需要看一些代碼來理解這一點。 – pmr 2012-08-07 12:23:22
