断言失败

Question

之后我在我班上添加了函数readcode我得到了错误 “C ++调试断言失败，表达式：_BLOCK_TYPE_IS_VALID（pHead - nblockUse）” 当我关闭程序时，我应该更改什么？

这是代码：

timecodeReader.cpp

 void TimecodeReader::readcode(Mat& im,int& istart,int & jstart,int d)


 {  


    int k,c,iakk;
   //String //
  code="";
  for(k=0;k<33;k++)
  {
    iakk=istart+k*d;
    c=checkBlock(im,iakk,jstart);
     if(c>245) 
        code=code+"1";
     else 
        code=code+"0";
}
  std::cout << code << std::endl;
//return code;

 }
