有人能讓我知道boost線程庫是否泄漏。在我看來,它確實: 谷歌說我應該使用boost線程和pthread來編譯我正在做的,而在版本1.40中這個問題已經解決了,但是我仍然有漏洞。請注意,這將編譯得很好,但會檢測到泄漏。Boost線程泄漏C++
#include <boost/thread.hpp>
#include <boost/date_time.hpp>
void t1(){}
int main(void){
boost::thread th1(t1);
th1.join();
return 1;
}
隨着Valgrind的我得到以下輸出

我也試圖與在以下網站上列出的代碼:http://antonym.org/2009/05/threading-with-boost---part-i-creating-threads.html 還是同樣的問題。
看看boost源文件中的src/pthread/Once.cpp。很明顯,它不會泄漏(只需查找它使用的pthread庫函數的定義)。 – Mankarse 2011-06-12 11:23:22
使用'std :: thread'而不是boost,代碼甚至不會運行;它終止於一個'std :: system_error'異常。 – 2011-06-12 11:41:04
只是嘗試在上面的鏈接代碼,你最有可能會看到valgrind – 2011-06-12 18:32:11
