奇怪的程序挂起,这在调试中意味着什么？

附上windbg后我发现了以下内容:

(1714.258): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.
eax=015b5c74 ebx=178a13e0 ecx=dddddddd edx=009a8ca0 esi=09fbf698 edi=09fbf594
eip=005ae2f7 esp=09fbf4a4 ebp=09fbf594 iopl=0         nv up ei ng nz na pe nc
cs=001b  ss=0023  ds=0023  es=0023  fs=003b  gs=0000             efl=00010286
TestApplication!std::_Container_base::_Orphan_all+0x57:
005ae2f7 c70100000000    mov     dword ptr [ecx],0    ds:0023:dddddddd=????????

调用堆栈:

TestApplication!std::_Container_base::_Orphan_all+0x57
TestApplication!std::vector >::operator=+0x37
TestApplication!boost::asio::detail::win_iocp_io_service::do_one+0x189
TestApplication!boost::asio::detail::win_iocp_io_service::run+0xa2
TestApplication!boost::asio::io_service::run+0x3a

如果您使用的是MSVC和Debug构建配置,0xdddddddd通常意味着您正在尝试访问释放的内存.调试CRT内存管理器填充可用内存0xdd.
