The information in this article applies to:

  • The Microsoft C/C++ Compiler (CL.EXE) included with: Microsoft Visual C++, 32-bit Edition, version 2.0

SYMPTOMS

The compiler may hang (stop processing) when compiling a template that includes a syntax error in the function declaration as shown in the samples in this article.

RESOLUTION

Press CTRL+BREAK to stop the build process and return the focus to Visual C++. Correcting the syntax error will allow the code to compile.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem was corrected in Microsoft Visual C++, 32-bit Edition, version 4.0.

MORE INFORMATION

The following samples can be used to reproduce the problem:

Sample Code 1

/* Compile options needed: none
*/
template <class T> 

T max(T a, T b>    // Note: ">" on right should be a ")"
    {
    return a;
    }

void main () {}

Sample Code 2

/* Compile options needed: none
*/
template<class TYPE, class ARG_TYPE> class CList { public: 
    TYPE* GetHead (void);
}; 

//
//   SYNTAX ERROR: "TYPE(" instead of "TYPE*"
//
template<class TYPE, class ARG_TYPE> inline TYPE( CList<TYPE, ARG_TYPE>::GetHead (void) { }
