我正在尝试valgrind来检测内存泄漏.它适用于堆泄漏(即来自malloc或new的内存分配).但是,它是否支持在Linux中检查mmap泄漏？

谢谢张

是的,这可能是你第三次看到这段代码,因为我问了另外两个关于它的问题(这个和这个)..代码很简单:

#include <vector>
int main() {
    std::vector<int> v;
}

然后我在Linux上使用Valgrind构建并运行它:

g++ test.cc && valgrind ./a.out
==8511== Memcheck, a memory error detector
...
==8511== HEAP SUMMARY:
==8511==     in use at exit: 72,704 bytes in 1 blocks
==8511==   total heap usage: 1 allocs, 0 frees, 72,704 bytes allocated
==8511==
==8511== LEAK SUMMARY:
==8511==    definitely lost: 0 bytes in 0 blocks
==8511==    indirectly lost: 0 bytes in 0 blocks
==8511==      possibly lost: 0 bytes in 0 blocks
==8511==    still …

代码相当简单：

#include <vector>
int main() {
    std::vector<int> v;
}

然后我用 Valgrind 构建并运行它：

g++ test.cc && valgrind ./a.out
