SYMPTOMS
Attempting to call a class constructor using a reference to a two dimensional array of objects will cause the compiler to incorrectly treat the array as a two dimensional array of references. In the sample below, the following errors will be incorrectly generated:
CAUSE
The compiler is interpreting
int (&iref)[10][10];
as if it was written:
int & iref[10][10];
It is not legal in C++ to use a pointer to a reference, so an array of references is also not legal.
STATUS
Microsoft has confirmed this to be a bug in the C/C++ compiler for MS-DOS, versions 7.0, 8.0, and 8.0c and the 32-bit C/C++ compiler, version 8.0. This problem was corrected in compiler version 9.0, included with Visual C++ version 2.0.
MORE INFORMATION
The following code can be used to demonstrate this problem.
Sample Code
/* Compile options needed: /c
*/
class X
{
int m_arr[10][10];
public:
X() {}
X( int (&iref)[10][10] ) {}
};
void main()
{
}
