为什么堆入口越来越大 [英] Why does heap entry become bigger and bigger

问题描述

Hi

while(TRUE)
{
//泄漏内存
void * p = HeapAlloc(GetProcessHeap()，0，500);
}

在windbg中，我注意到以该模式显示的堆条目(无论是在
调试模式下还是在释放模式下)

前几个条目
0037baf0:00210. 00210 [101]-忙(1f4)
是可以接受的.

为什么分配越来越大?

Hi

while (TRUE)
{
   // Leak the memory
   void* p = HeapAlloc(GetProcessHeap(), 0, 500);
}

In windbg, I notice that the heap entries shown in this pattern (whether in
debug mode or in release mode)

        0037aa70: 00210 . 00210 [101] - busy (1f4)
        0037ac80: 00210 . 00210 [101] - busy (1f4)
        0037ae90: 00210 . 00210 [101] - busy (1f4)

        003bc430: 04010 . 04010 [101] - busy (3ff8) Internal

...

        01a50090: 40010 . 40010 [101] - busy (3fff8) Internal
        01a900a0: 40010 . 40010 [101] - busy (3fff8) Internal
        01ad00b0: 40010 . 40010 [101] - busy (3fff8) Internal
        01b100c0: 40010 . 40010 [101] - busy (3fff8) Internal
        01b500d0: 40010 . 40010 [101] - busy (3fff8) Internal
        01b900e0: 40010 . 40010 [101] - busy (3fff8) Internal

        01c10100: 40010 . 40010 [101] - busy (3fff8) Internal
        01c50110: 40010 . 40010 [101] - busy (3fff8) Internal

The first few entries
        0037baf0: 00210 . 00210 [101] - busy (1f4)
are acceptable.

But why does the allocation become bigger and bigger?

        00394390: 04010 . 04010 [101] - busy (3ff8) Internal
        ...
        01c10100: 40010 . 40010 [101] - busy (3fff8) Internal

Thanks
