The fscale implementation uses floatx80_scalbn for the final scaling operation. floatx80_scalbn ends up rounding the result using the dynamic rounding precision configured for the FPU. But only a limited set of x87 floating-point instructions are supposed to respect the dynamic rounding precision, and fscale is not in that set. Fix the implementation to save and restore the rounding precision around the call to floatx80_scalbn.
