They only work on x86 processors, almost by definition: SSE stands for a certain instruction set. So one would need to check whether the problem occurs for other architectures. I would assume that it happens on all 32 bit architectures, in particular armhf. Their code is too fragile: One should not rely on fine details of the processor architecture or instruction set to hope for an expected rounding behaviour. Andreas
