proposed fix

Could you try this fix? Note the error is actually with the _reference_, not
the actual driver code (this is because we want no denormals and are switching
them off in the driver), so llvm updates aren't going to do anything. I guess
that not everyone gets exactly the same error is just due to what the math
libraries / compilers are doing (they expect "ordinary" denormal handling,
hence they are not required to honor our differently set cpu flags and the
results are therefore kinda undefined).
In any case, this is really more of a cosmetic error.
