APPLIES TO


 * Microsoft Visual C++ .NET 2003 Standard Edition

SYMPTOMS
After you port a Visual C++ application from Microsoft Visual Studio .NET 2002 (or earlier) to Visual Studio .NET 2003, you may experience exceptions that floating point assignments in C++ code generate. You may also experience exceptions when you enable the exception mechanism of the floating-point unit.



CAUSE
Floating point assignments previously generated &quot;mov&quot; instructions, and now they generate floating point instructions.



RESOLUTION
Use this hotfix so that the code that you generate has &quot;mov&quot; instructions for floating point assignments instead of floating point instructions. To use this hotfix, you must install it and then rebuild your application with the &quot;-nox87copy&quot; compiler flag.
