internal compiling error when using template class

Question

I am trying to migrate a project from VS2008 to VS2013, The project compiles and works in VS2008, unfortunately I suddenly receive an "An internal error has occurred in the compiler" when compiling the same code with VS2013. The error occurs when trying the call a method of a template class

void func(const CMatrix<CSegment>& segments) const
{
    int row, col;
    row = segments.NumOfRows(); //error points to here
    col = segments.NumOfColumns(); // if I remove the above line then the error points to here
}

and CMatrix is defined like so:

class CBaseMatrix
{
public:
    CBaseMatrix() {};
    virtual ~CBaseMatrix() {};
    virtual void Resize(const int row, const int col) = 0;
    virtual inline int Size()   const = 0;
    virtual inline int NumOfColumns() const = 0;
    virtual inline int NumOfRows() const = 0;
};


template <class T> 
class CMatrix : public CBaseMatrix
{   
public:

    CMatrix() : 
    m_rawBuff(0),
    m_rawBuffSize(0), 
    m_columns(0), 
    m_rows(0), 
    m_data(0) 
    {};

CMatrix(const CMatrix& matrix):
{
    *this = matrix;
};

    inline int NumOfColumns()   const {return(m_columns);};

    inline int NumOfRows()  const {return(m_rows);};

    inline int Size()   const {return(m_data.size());};

private:
    int m_columns;
    int m_rows;
    vector<T> m_data;
    T*  m_rawBuff ;
    int m_rawBuffSize ;

};

I cannot find any problem with the code, and the error itself is not very informative.

I hope that I miss something or that someone encountered a similar problem and has an idea how to solve it.

Thanks.

Answer 1

I have no idea how the code would work under any compiler as:

void func(const CMatrix<CSegment>& segment) const
{
    int row, col;
    row = segments.NumOfRows(); //error points to here
    col = segments.NumOfColumns(); 
}

Passes in a variable called segment and the code tries to access one called segment s .

Try changing the parameter name to segments.

Answer 2

Well, I found out what the problem was, notice that in the original code:

CMatrix(const CMatrix& matrix):
{
    *this = matrix;
};

I have ":" after the constructor, but the initialization list is empty, Somehow that caused the compiler to crush.

after removing them:

CMatrix(const CMatrix& matrix)
{
    *this = matrix;
};

everything works!

Note that I submitted the error to Microsoft, and hopefully they will take care of this in the next update, but in the meanwhile, I leave my solution here in case anyone else encounter this problem.
