When you use Microsoft Visual Studio .NET 2003 to build a Microsoft Visual C++ project that performs calculations, the resulting application generates incorrect calculation results. This problem occurs when you use the /O2 command-line option for performance optimization.
This problem is caused by the way that the Visual C++ 2003 compiler creates the optimized project output. In some cases, performance optimization produces incorrect results.
