高手请进，看如下代码，怪事连连

[bobo2261]

下面是定时器的回调函数

int
OnGageTimer( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t *cbinfo )

{
//char buf[10];
//static int count = 0;
/* eliminate 'unreferenced' warnings */
widget = widget, apinfo = apinfo, cbinfo = cbinfo;

//memset(buf,10,0);

//sprintf(buf,"%d",count);

//PtSetResource(ABW_label_timer,Pt_ARG_TEXT_STRING,buf,0);
//count++;

char x[1024];
//memset(temp,0,);

g_memdb.ReadFreeRegion(0,(char *)&g_gage_overview,sizeof(g_gage_overview));

return( Pt_CONTINUE );
}

g_memdb.ReadFreeRegion()函数之前必须有char x[1024];的声明，否则程序会自动跳出去，不能正确执行，不知道问题出在哪里？
