Workaround:

Hide
Either use --fp_mode=strict or update include/math.h with below:
__inline float __relaxed_powf(float x, float y)
{
  float log2ofx = __log2(x);
  float log2ofxtimesy = log2ofx * y;
  float exp2foflog2ofxtimesy = exp2f(log2ofxtimesy);
  return log2ofxtimesy > 0 ? exp2foflog2ofxtimesy : 1.0f / exp2foflog2ofxtimesy;
}

Release Notes:
Using --tmu_support=tmu1 --fp_mode=relaxed, below math.h routine did not properly handle a negative result for log2(x): __inline...
