我使用boost_log开发* nix CLI应用程序。几天前我将main（）的所有代码移到了.so库中，之后每次我的应用程序退出时都会崩溃（请看下面）。它并不重要，但看起来很讨厌，所以我很想摆脱它。任何建议将不胜感激。
我尝试过GDB，但没有帮助（下面输出）。

您正在查看Static Initialization Order Fiasco.
尽管有名称，但它也适用于破坏全局对象的顺序。由于订单可能在库对象文件的重组中发生了变化，因此很可能最终会破坏后使用。
查找析构函数内的日志记录。避免使用全局/名称空间范围静态。
尽管如此，我不认为升级日志中存在未知的双重免费问题，我认为这与我如何使用它有关。
确实
