Should we consider adding -mfpmath=sse to CXXFLAGS (on CPUs that support it) if we want a little bit more floating point numerical stability?
(although, some performance benchmarks are required on various CPUs to ensure we're not slowing down significantly)

Do you mean, it will be impossible to use python bindings without a patch and a version bump for pybindgen?
