前提，我正在使用Eclipse。 在我寻求多线程应用程序的调试时，我首先运行了valgrind memcheck，它给了我一堆错误，无法识别这些错误来自哪些代码行。 然后我创建了一个配置文件以在Debug构建中使用valgrind，它给了我一个错误 “读取大小为1的无效”指向源代码中的一行，允许我修复它。现在在Debug构建上运行的valgrind没有给我任何错误，但如果我尝试在Release版本上运行valgrind，我会收到错误，这些错误无法查明。

为什么这些错误只出现在Release版本中？我该怎么做才能获得更多信息？ 此外，我的多线程程序挂在某个地方，这是尝试找出问题所在的正确方法吗？
