C++ 根据Valgrind，临时std：：管柱泄漏导致的共享ptr？

Valgrind告诉我这条线肯定在漏水

std::shared_ptr<std::string> pName(new string);

Edit2（已解决）：事实证明，问题出现在我的

PriorityQueue.h

文件中。Valgrind的错误有些误导。我错误地使用了

std:：allocator

。使用分配器销毁以前分配的数组中的项时，必须调用分配器。销毁（myArray+i）for

语句是在自找麻烦。我同意Joachim的观点。有时，您需要动态分配，当这种情况发生时，智能指针就是猫的胡子。然而，在大多数情况下，保持它的简单性并充分利用它。C++是复杂的，但它具有java不具备的主要特性；母语的破坏是可预测的。这正是RAII如此强大的原因，我再怎么强调它有多好也不为过。开发利用它对你有利的技能。还在看你的代码。
