(This problem affects only the 圆4 libraries.) This causes the math library to revert to using the non-FMA3 implementations.To code and develop applications you usually need what is known as an integrated development environment or IDE. The function _set_FMA3_enable(0) is declared in, and it's available only when you build for 圆4. You can query whether the system supports AVX instructions by calling GetEnabledXStateFeatures and disabling AVX in the CRT explicitly by calling _set_FMA3_enable(0).įor more information, see Working with XState Contexton the MSDN website. To work around this problem, disable FMA3 in the math library if you are affected by this problem.

For more information, see the following Microsoft Knowledge Base article:ģ179560 Update for Visual C++ 2013 and Visual C++ Redistributable Package Workaround To update the dynamically linked Visual C++ 2013 C Runtime DLLs, an updated redistributable is available. It is available at the Microsoft Download Center website: To update the statically linked Visual C++ 2013 C Runtime, the 3174417 hotfix is released as a download-only update and isn't distributed through Windows Update. The problem was fixed before the initial release of the Universal CRT that is used by Visual C++ 2015. Note This problem does not affect older versions of the Visual C++ C Runtime (Visual C++ 2012 and earlier versions). If your affected C++ binaries statically link the Visual C++ 2013 C Runtime, you must update your installation of Visual Studio 2013 by installing the 3174417 hotfix and rebuilding and redeploying the affected binaries.

If all affected C++ binaries that are built by using Visual C++ 2013 use the C Runtime DLL (msvcr120.dll), install the updated Microsoft Visual C++ 2013 Redistributable – 0.0 or a later version. This issue occurs because the Visual C++ 2013 圆4 C Runtime does not check whether the operating system supports AVX state saving before it tries to run AVX or FMA3 instructions. Visual Studio 2013 RTM: C++ 圆4 code generation bug for AVX2 instructions Cause X64 log() function uses vpsrlq AVX instruction without regard to operating system (so it crashes on Vista 圆4) This problem has been reported on Microsoft Connect: Note Windows PE does not support AVX state saving. In the Windows Preinstall Environment (Windows PE)

If AVX state saving is explicitly disabled in the operating system boot configuration On an old version of the Windows operating system that does not support AVX state saving (for example, Windows Vista) if it's used on a computer that supports the AVX instruction set

This problem is most likely to occur in the following scenarios:

Affected functions include log, log10, and pow, and others. If the instructions are not available for use, calls to these functions cause an illegal instruction exception (0xc000001d). This occurs because some floating-point math library functions in the Visual C++ 2013 圆4 C Runtime (CRT) do not correctly check whether certain AVX and FMA3 instructions are available before the functions try to use them. When you build a program by using Microsoft Visual C++ 2013, the program crashes and you receive an 'Illegal Instruction' exception.
