When setting cmake option ENABLE_FMA=ON then -mfma compiler option is added (only on compilers that support it). This gives better performance, but slightly different results. And because of that some unit tests don't pass (Wendling gamma index and linear interpolation). Check if enabling FMA gives more or less accurate results.
