有人能让我知道boost线程库是否泄漏。在我看来,它确实: 谷歌说我应该使用boost线程和pthread来编译我正在做的,而在版本1.40中这个问题已经解决了,但是我仍然有漏洞。请注意,这将编译得很好,但会检测到泄漏。Boost线程泄漏C++
#include <boost/thread.hpp>
#include <boost/date_time.hpp>
void t1(){}
int main(void){
boost::thread th1(t1);
th1.join();
return 1;
}
随着Valgrind的我得到以下输出

我也试图与在以下网站上列出的代码:http://antonym.org/2009/05/threading-with-boost---part-i-creating-threads.html 还是同样的问题。
看看boost源文件中的src/pthread/Once.cpp。很明显,它不会泄漏(只需查找它使用的pthread库函数的定义)。 – Mankarse 2011-06-12 11:23:22
使用'std :: thread'而不是boost,代码甚至不会运行;它终止于一个'std :: system_error'异常。 – 2011-06-12 11:41:04
只是尝试在上面的链接代码,你最有可能会看到valgrind – 2011-06-12 18:32:11
