Consider the following scenario:
- In Microsoft Visual Studio 2005, you create a C++ application.
- You do not specify the /fp:except option. Therefore, floating-point exceptions are not enabled in the C++ application.
- You do not specify the /fp:strict option. Therefore, the strict floating-point model is not enabled in the C++ application.
- An inline function in the C++ application returns an uninitialized floating-point variable.
- You compile the C++ application.
In this scenario, a floating-point exception may occur when you run the C++ application. Additionally, you may receive the following error message:
0xC0000090: Floating-point invalid operation.
This problem may occur in debug builds and in release builds.
This problem occurs when the uninitialized floating-point variable loads a memory location that contains a signaling not-a-number (NaN) value.
