!!! Committed last page of the stack (0x00001003) or invalid stack pointer (0x000510bc), SEH bypassed, thread terminated !!!

 

其中关键信息：
(1) Exception ‘User Stack Overflow‘ (0xfffffffd)
(2) !!! Committed last page of the stack (0x00001003) or invalid stack pointer (0x000510bc), SEH bypassed, thread terminated !!!

由于是偶尔出现的问题，目前还没有找到引起上述异常信息的原因。

修改了工程的属性中：
配置属性->链接器->系统 下的:
(1) 堆栈保留大小 65536 修改为 131072
(2) 堆栈提交大小 4096 修改为 8192
都扩大了2倍。
以下修改是否有效，还需要进一步测试与验证。
