获取分段错误或代码停止

Question

当我运行我的代码（它是用root编写的，这是基于c ++的编程语言）时，要么它给了我分段错误，要么它停留在某一点，但我无法弄清楚它为什么会发生。以下是我的代码的详细信息。

DataArray* g[MaxNumbersOfDetDir];
for(Int_t i=0; i<MaxNumbersOfDetDir; i++)
     {
     if (testCout)cout<<"test"<<endl;
     g[i] = new DataArray((const int)PossibleHits[i]);
     if (testCout)cout<<"Possible hits = "<<PossibleHits[i]<<"\t g[i] = "<<g[i]<<endl;
     }

此DataArray类定义为

//Constructor with number of elements to allocate
DataArray::DataArray(const int maxNumOfChannels) 
  : TObject(), nallocated(0), nch(0), ch(0)
{ 
if (COUT)cout<<"in Dataarray cpp 11"<<endl;
  if (maxNumOfChannels > 0)  
    {   
if (COUT)cout<<"in Dataarray cpp 22 = "<<maxNumOfChannels<<endl;
      ch = new chtype[maxNumOfChannels];
if (COUT)cout<<"in Dataarray cpp 22 ch = "<<ch<<endl;
      nallocated = maxNumOfChannels;
if (COUT){      std::cout << "New object with " << nallocated 
        << " elements. "<<ch<<"\t Object at " 
        << (this) << std::endl; }
    };  
} 

所以，我的代码停在

行

 ch = new chtype[maxNumOfChannels];

提供的信息是否充足，还是应该提供更多信息？
