帮忙推荐个内存泄露检测工具吧^_^

Ediml

非图形的
谢谢！
用了一下valgrind
太晕了
完全看不懂它输出来的那些东西

zwylinux

valgrind的输出很明了了吧
mpr也可以

sjh_311

purify不知道是不是图形的

ruchong

一直用vargrind
有什么好的图形化的推荐一下......

lanneret_sky

linux下还真不多呀

while(1)

什么地方看不懂？

Ediml

我贴一下我的检测结果吧

Use of uninitialised value of size 4
使用未初始化的内存

我那是个void* 结构
是别的函数返回来的
没法初始化啊
