test dword ptr [eax],eax ; probe page. 分页出错

Windows系统默认分页大小为1M 1024 *1024，当申请的空间大于1M时就会出现如下问题：

1.在Debug下调试程序，出现如下错误：test dword ptr [eax],eax ; probe page.

Stack overflow

2.通过debug就会进入以下文件chkask.asm

;_chkstk – check stack upon procedure entry

;

;Purpose:

; Provide stack checking on procedure entry. Method is to simply probe

; each page of memory required for the stack in descending order. This

; causes the necessary pages of memory to be allocated via the guard

; page scheme, if possible. In the event of failure, the OS raises the

; _XCPT_UNABLE_TO_GROW_STACK exception.

;

; NOTE: Currently, the (EAX < _PAGESIZE_) code path falls through

; to the "lastpage" label of the (EAX >= _PAGESIZE_) code path. This

; is small; a minor speed optimization would be to special case

; this up top. This would avoid the painful save/restore of

; ecx and would shorten the code path by 4-6 instructions.

;

;Entry:

; EAX = size of local frame

;

;Exit:

; ESP = new stackframe, if successful

;

;Uses:

; EAX

;

;Exceptions:

; _XCPT_GUARD_PAGE_VIOLATION – May be raised on a page probe. NEVER TRAP

; THIS!!!! It is used by the OS to grow the

; stack on demand.

; _XCPT_UNABLE_TO_GROW_STACK – The stack cannot be grown. More precisely,

; the attempt by the OS memory manager to

; allocate another guard page in response

; to a _XCPT_GUARD_PAGE_VIOLATION has

; failed.

3.解决方法：1.减小申请空间的大小

2.大栈空间的大小 方法为：项目->属性->链接器->系统->堆栈保留大小
