程序的结构是
+------+
|Parent|------------>死亡
+------+
|
|-------[fork()]---->子进程 1------->死亡
|
|-------[fork()]---->子进程 2------->死亡
|
....
....
|
|-------[fork()]---->子进程 n------->死亡
测试的时候Parent进程没有问题，然而三个子进程每一个都报告： MEMWATCH detected 1 anomalies
但是memWatch.log文件里面的日志又是：

显示的四个进程都没有问题，Unfreed bytes total这一项都是0
我就不明白了，这到底是有没有内存遗漏呢？
