KB116240 - FIX: Compiler Errors Initializing const Reference to an Array

MORE INFORMATION

The sample code below demonstrates the problem. Compiling it yields at least one of the following error messages:

error C2607: 'initializing' : cannot implicitly convert a 'int [3][2]' to a 'int __near &[3][2]' that is not const

error C2561: 'getMtx' : function must return a value

To work around the problem, use each commented line in the program to replace the line immediately above it.

Note: Simply removing the const specifier from the getMtx function's return type eliminates the problem.

Sample Code

/* Compile options needed: none
*/ 
typedef int Matrix[3][2];

class Data
{
    Matrix Mtx;
    const Matrix& getMtx();
    // const int (&getMtx() const)[3][2];
};

inline const Matrix& Data::getMtx()
// inline const int (&Data::getMtx() const)[3][2]
{
    return Data::Mtx;
    // return (const int (&)[3][2])Data::Mtx[0][0];
}
