The simplest reason might be a corrupted binary image. You shouldn't get assembly instructions reserved for ring 0 fom a regular (i.e. non-driver) build.

Thanks,<br />

I guess the error is the result of copying strings, probably one of the strings overflow the destination buffer corrupting the stack.<br />

Ps: Now comes the hard part, finding the guilty copy.<br />

We have a Visual C++ program and in execution sometimes it throws the exception C000001D. Which is defined as either STATUS_ILLEGAL_INSTRUCTION<wbr /> or EXCEPTION_ILLEGAL_INSTRUCT<wbr />ION.<br />

What can be causing this?<br />

What are possible reasons for exception C000001D STATUS_ILLEGAL_INSTRUCTION EXCEPTION_ILLEGAL_INSTRUCTION ?

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.

Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. It features tools for developing and debugging C++ code, especially code written for the Microsoft Windows API, the DirectX API, and the Microsoft .NET Framework. Many applications require redistributable Visual C++ packages to function correctly and are often installed independently of applications, allowing multiple applications to make use of the package while only having to install it once
