求教大神！！！
V831方案用MINIGUI去实现界面显示。程序编译成功，但运行到窗口创建处出错。
部分代码：
int main (int args, const char* arg[])
{
MSG Msg;
MAINWINCREATE CreateInfo;
HWND hMainWnd;

#ifdef _MGRM_PROCESSES
JoinLayer (NAME_DEF_LAYER, arg[0], 0, 0);
#endif

InitCreateInfo (&CreateInfo);
sm_debug("CreateMainWindow\n");

hMainWnd = CreateMainWindow (&CreateInfo);
if (hMainWnd == HWND_INVALID){
	
	sm_error("CreateMainWindow fail\n");
    return -1;
}
sm_debug("CreateMainWindow sucess\n");

while (GetMessage (&Msg, hMainWnd)) {
    DispatchMessage (&Msg);
}

MainWindowThreadCleanup (hMainWnd);
return 0;

}

创建窗口原函数：
HWND GUIAPI CreateMainWindowEx (PMAINWINCREATE pCreateInfo,
const char* werdr_name, const WINDOW_ELEMENT_ATTR* we_attrs,
const char* window_name, const char* layer_name)
{
//
PMAINWIN pWin;
fprintf(stderr,"CreateMainWindowEx run zth\n");

if (pCreateInfo == NULL) {

    return HWND_INVALID;
}

if (!(pWin = calloc(1, sizeof(MAINWIN)))) {

    return HWND_INVALID;
}
fprintf(stderr,"CreateMainWindowEx	run111 zth\n");

#ifdef _MGRM_THREADS
fprintf(stderr,"CreateMainWindowEx run 11\n");

if (pCreateInfo->hHosting == HWND_DESKTOP || pCreateInfo->hHosting == 0) {
    /*
     ** Create thread infomation and message queue for this new main window.
     */
    if ((pWin->pMessages = GetMsgQueueThisThread ()) == NULL) {
        if (!(pWin->pMessages = mg_InitMsgQueueThisThread ()) ) {
            free (pWin);

            return HWND_INVALID;
        }
        pWin->pMessages->pRootMainWin = pWin;
    }
    else {
        /* Already have a top level main window, in case of user have set 
           a wrong hosting window */
        pWin->pHosting = pWin->pMessages->pRootMainWin;
    }
}
else {
    pWin->pMessages = GetMsgQueueThisThread ();
    if (pWin->pMessages != kernel_GetMsgQueue (pCreateInfo->hHosting) ||
            pWin->pMessages == NULL) {
        free (pWin);

        return HWND_INVALID;
    }
}
fprintf(stderr,"CreateMainWindowEx  run 22");

if (pWin->pHosting == NULL)
    pWin->pHosting = gui_GetMainWindowPtrOfControl (pCreateInfo->hHosting);
/* leave the pHosting is NULL for the first window of this thread. */

#else
fprintf(stderr,"CreateMainWindowEx runzth 11\n");

pWin->pHosting = gui_GetMainWindowPtrOfControl (pCreateInfo->hHosting);
if (pWin->pHosting == NULL)
    pWin->pHosting = __mg_dsk_win;

报错信息：
dbg line[80 ] sample_philips_recorder.c CreateMainWindow
CreateMainWindowEx run zth
CreateMainWindowEx run111 zth
CreateMainWindowEx run 11
Segmentation fault (core dumped)

求教原因！！！！
