FIX: The fmod function returns an indeterminate (IND) value instead of the expected floating-point value in a 64-bit Visual C++ 2008 SP1 application

Symptoms

Consider the following scenario:

You run a 64-bit Microsoft Visual C++ 2008 Service Pack 1 (SP1) application.
The application is linked with floating-point modules that are written in assembly code, or that are built with a non-Microsoft C++ compiler.
The application calls a floating-point function in an external module that raises an x87 exception, and then calls the Visual Studio C-Runtime fmod function.

In this scenario, the returned value of the fmod function is an indeterminate (IND) value instead of the expected floating-point value.

For example, you may encounter the problem when the following conditions are true:

The external module that executes floating-point code was generated by the Intel C++ compiler.
The external module is executed on non-Intel x64 processors, such as AMD processors or VIA processors.

Note This problem also occurs when you use the fmodf function in the same scenario.

Cause

This problem occurs because of an issue in the assembly code in the 64-bit version of the fmod function. The function incorrectly treats some irrelevant flags as errors.

Workaround

To work around this problem, assemble a wrapper function that calls an fnclex instruction before the wrapper function calls the fmod function. The following code is an example of how to assemble the wrapper function:

public  <Function Name> <Function Name>  proc     fnclex     call fmod     ret <Function Name>  endp
