我是valgrind的新手。我在Ubuntu 15.10上使用Qt 5.5.1库用C ++编写了一个程序。我正在使用Qt Creator和Debug构建集。我使用Valgrind使用以下命令检查内存泄漏：
valgrind --leak-check=yes --track-origins=yes ./texteditor

从上面的消息中，没有任何内容指向myProgram的位置。这是来自Qt和其他图书馆还是我错过了指向myProgram的内容？

默认情况下，Valgrind仅显示调用堆栈的前12个条目，但可以使用--num-callers=xx参数更改此条目。您自己的程序代码中的函数可能会在堆栈中进一步下降。
