该块中提到的所有功能都是库函数.我怎样才能纠正这个内存泄漏？

它列在" 仍可达 "类别下.(还有4个,非常相似,但尺寸各异)

 630 bytes in 1 blocks are still reachable in loss record 5 of 5

Catch:一旦我运行我的程序,它没有内存泄漏,但它在Valgrind输出中有一个额外的行,之前没有出现:

由于munmap()而丢弃/lib/libgcc_s-4.4.4-20100630.so.1中的0x5296fa0-0x52af438处的syms

如果泄漏无法纠正,有人可以解释为什么munmap()行导致Valgrind报告0"仍然可达"泄漏？

这是一个最小的测试样本:

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
