DOCUMENT:Q115708 26-JUL-2001 [visualc] TITLE :FIX: C++ Compiler Treats &array[][] as 2-D Array of References PRODUCT :Microsoft C Compiler PROD/VER: OPER/SYS: KEYWORDS:kbCompiler kbCPPonly kbVCkbbuglist kbfixlist ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft C/C++ Compiler (CL.EXE), included with: - Microsoft C/C++ for MS-DOS, version 7.0 - Microsoft Visual C++, versions 1.0, 1.5 - *EDITOR Please do not choose this product*Microsoft Visual C++ 32-bit Edition* use 241, 265, 225, version 1.0 ------------------------------------------------------------------------------- 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: test.cpp(6) : error C2234: arrays of references are illegal test.cpp(6) : error C2511: '__ctor' : overloaded member function not found in 'X' 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() { } Additional query words: 7.00 8.00 8.00c 1.00 1.50 ====================================================================== Keywords : kbCompiler kbCPPonly kbVC kbbuglist kbfixlist Technology : kbVCsearch kbAudDeveloper kbCVCComp Issue type : kbbug Solution Type : kbfix ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
