当试图获取某个进程的线程的调用堆栈时，我总是得到一个相同的帧，尽管它肯定有更多的帧（至少5个帧）。
StackWalk 64（）总是在第一次调用时成功-返回一个帧：

AddrPC.Offset = 18446744072850558156

但是，在第二次调用时，它立即失败，错误id为998-ERROR_NOACCESS（正如MSDN所说，这个错误可能不是由于这个调用引起的）。
此外，尝试使用SymFromAddr（）将此地址解析为其符号名称失败，并显示错误126-ERROR_MOD_NOT_FOUND（在成功调用SymInitialize（m_processHandler，NULL，TRUE）之后）。
下面是代码：

#ifdef _M_IX86
  //
  // Disable global optimization and ignore /GS waning caused by
  // inline assembly.
  //
  #pragma optimize( "g", off )
  #pragma warning( push )
  #pragma warning( disable : 4748 )
#endif

bool EchoProfiler::getThreadStackTrace(__in HANDLE h_thread, __out vector<DWORD64> &framesVec)
{
CONTEXT threadContext;
if (GetThreadContext(h_thread, &threadContext) == 0)
{
    cout << "Error: GetThreadContext() failed with error ID " << GetLastError() << endl;
    return false;
}

//initialize stack frame
DWORD MachineType;
STACKFRAME64 StackFrame;
ZeroMemory( &StackFrame, sizeof( STACKFRAME64 ) );

MachineType                 = IMAGE_FILE_MACHINE_I386;
StackFrame.AddrPC.Offset    = threadContext.Eip;
StackFrame.AddrPC.Mode      = AddrModeFlat;
StackFrame.AddrFrame.Offset = threadContext.Ebp;
StackFrame.AddrFrame.Mode   = AddrModeFlat;
StackFrame.AddrStack.Offset = threadContext.Esp;
StackFrame.AddrStack.Mode   = AddrModeFlat;

PVOID contextRec = (MachineType == IMAGE_FILE_MACHINE_I386) ? NULL : &threadContext;
int i=0;
// enumerate all the frames in the stack
for (i=1 ; ; i++)
{
    if (StackWalk64( MachineType, targetProcessHandler, h_thread, &StackFrame,
        contextRec, NULL, SymFunctionTableAccess64, SymGetModuleBase64, NULL ) == false)
    {
        // in case it failed or we have finished walking the stack.
        cout << "Error: StackWalk64() failed with error ID " << GetLastError() << endl;
        i--;
        break;
        // return false;
    }

    if ( StackFrame.AddrPC.Offset != 0 )
    {
        // Valid frame.
        cout << "Frame #" << i << " address - " << StackFrame.AddrPC.Offset << endl;
        framesVec.push_back(StackFrame.AddrPC.Offset);
    }
    else
    {
        // Base reached.
        break;
    }
}

//cout << "StackWalk64 found " << i << " stack frames:" << endl;
//i = 1;
//for (FramesConstItr itr=framesVec.begin() ; itr != framesVec.end() ; itr++ , i++)
//  cout << i << " - " << *itr << endl;

return true;
}

#ifdef _M_IX86
  #pragma warning( pop )
  #pragma optimize( "g", on )
#endif

会是什么呢？
