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。
