It is weird since in 6 years working with shaders (both in FX Composer and directly) I've never had a video driver crash, let alone BSOD (I don't even know how it looks like now). Maybe I've been using a wrong operating system?

Seriously though, Cg, HLSL and GLSL are restrictive enough, there is little you can do to force the crash. Sure, there are ways to mess up with the API, but I don't think using badly written shaders is one of them.
