BUG: Erroneous C2352 Generated When Using typedef'd Base Class

Q115528

7.00 | 1.00 1.50 MS-DOS | WINDOWS kbtool kbbuglist ---------------------------------------------------------------------- The information in this article applies to: - The Microsoft C/C++ Compiler (CL.EXE), included with: - Microsoft C/C++ for MS-DOS, version 7.0 - Microsoft Visual C++ for Windows, versions 1.0 and 1.5 ---------------------------------------------------------------------- SYMPTOMS ======== When compiling code using a typedef'd base class, as shown in the sample code below, the compiler incorrectly generates the following error: error C2352: 'Base::Print' : illegal call of nonstatic member function When compiling the same code under C/C++, version 7.0, the following error message is generated instead of the C2352 message: error C2653: 'Superclass' : is not a class name STATUS ====== Microsoft has confirmed this to be a bug with the C/C++ compiler, versions 7.0, 8.0, and 8.0c. We are researching the problem and will post new information here in the Microsoft Knowledge Base as soon as it becomes available. This is not a problem in the 32-bit compilers. Sample Code ----------- /* Compile options needed: /c */ #include <iostream.h> class Base { int i; public: Base() : i(123) {} virtual void Print() { cout << i << '\n'; } }; class Derivd : public Base { double d; typedef Base Superclass; public: Derivd() : d(3.14159) {} virtual void Print1() { Base::Print(); cout << d << '\n'; } virtual void Print2() { Superclass::Print(); cout << d << '\n'; } }; main() { Derivd test; test.Print(); return 0; } Additional reference words: 1.00 1.50 7.00 8.00 8.00c KBCategory: kbtool kbbuglist KBSubcategory: CPPIss
