Z = sa ^ random_mask_vec8[o:len(sa)+o]

Hi everyone,

I’m using benchmark to do experiment in gun-radio. But at the receiver
side, I met this problem sometimes, the terminal says " z = sa ^
random_mask_vec8[o:len(sa)+o]. ValueError: operands could not be
broadcast together with shapes (4087) (4081)."

I tried to print the whiten parameter s and o. In the first packets, s
is always 8 and o is 0. But then suddently, s change to 4087 and o is
15, so this ValueError shows up.

Actually, I’m not aware that I am changing any settings, but this
problem come up now and then. Sometimes it is fine, sometimes not. Has
anyone come across this problem before?
