Nice catch. They are identical. I repeated the compilations this morning with/without - msse4.1 and the result is indeed identical. In fact, it is the same when I omit *both* - msse2 and -msse4.1. I notice also that nowhere does the code reference the matrix computed. I wondered whether all that code was being optimized away -- so I added code to reference it: std::cout << "Element[0][0] = " << yuv2rgb_bt601(0,0) << "\n"; However, there is no change: the binary is identical regardless of the -m options. So I'm back to square 1, very confused by your crash. -Steve
