Largest free region(最大可分配的内存块空间)
------------- windbg 中对其动态调试 示例 --------------------
一. 查看初始的堆状态
!heap -s
二. 统计一下这个堆里的内存分配情况，发现 1000 字节的内存分配占了 86.97%，目标就锁定它了。
!heap -stat -h 00230000
size #blocks total ( %) (percent of total busy bytes)
1000 158 - 158000 (86.97)
三. 看一下都是哪些堆申请的
!heap -flt s 1000
四. 挑几个地址看一下调用栈
!heap -p -a 0303aec0
address 0303aec0 found in
_HEAP @ 230000
