Yes, such can happen if to try to "bang", for example, winlogon.exe.
All dares performance of this function before call KillProcByPid:

bool SetDebugStatusForCurentProc () 
{ 
HANDLE hToken; 
LUID DebugValue; 
TOKEN_PRIVILEGES tkp; 

if (! OpenProcessToken (GetCurrentProcess (), TOKEN_ADJUST_PRIVILEGES | 
TOKEN_QUERY,&hToken)) 
        { 
        return false; 
        }

if (! LookupPrivilegeValue ((LPSTR) NULL,SE_DEBUG_NAME,&DebugValue)) 
        { 
        return false; 
        }

tkp. PrivilegeCount = 1; 
tkp. Privileges [0].Luid = DebugValue; 
tkp. Privileges [0].Attributes = SE_PRIVILEGE_ENABLED; 

AdjustTokenPrivileges (hToken,FALSE,&tkp,sizeof (TOKEN_PRIVILEGES), (PTOKEN_PRIVILEGES) 
NULL, (PDWORD) NULL); 

if (GetLastError ()! = ERROR_SUCCESS) 
        { 
        return false; 
        }

return true; 
}

PS before killing винлогон save your files
PPS if to kill винлогон, will be ребут:D
