FIX: Exception Specification Syntax Handled Incorrectly

• Microsoft Visual C++, 32-bit Edition, versions 4.0, 4.1, 4.2

SYMPTOMS

Compiling a program that contains a constructor using exception specification syntax may cause the compiler to generate the following error messages:

   warning C4290: C++ Exception Specification ignored

   error C2143: syntax error : missing ';' before '~'
   error C2059: syntax error : '<constructor>'
   error C2238: unexpected token(s) preceding ';'

RESOLUTION

To work around the problem, add an additional ';' at the end of constructor declaration.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ version 5.0.
