求教Vlib的库函数VLIB_createConnectedComponentsList（）经常卡死问题！

 Create32BitPackedBinImage(Temp_Image,     final,     imageHeight,     imageInputData,      threshold);

 // 初始化  ccHandleSize  = VLIB_GetSizeOfCCHandle();  handle   = (VLIB_CCHandle*)MEM_alloc(ddr2Heap,ccHandleSize,8);  VLIB_initConnectedComponentsList(handle,      primaryBuff1,      48*1024,      primaryBuff2,      48*1024,      overFlowBuff1,      48*1024,      overFlowBuff2,      48*1024);

 status=VLIB_createConnectedComponentsList(handle,      (Uint16)final,      (Uint16)imageHeight,      (int*)imageInputData,      400,      1);// 8联通1  4联通0  

if(status!= 0)   printf("Faile!\n");

程序经常卡在红色位置，有时能够顺利执行整个连通域此操作，但有时会在红色库函数处卡死，求教大神解答 感激不尽！
