Details:

This is almost like bug #53458
in MATLAB,


>> bitxor(-10,20)
Error using bitxor
Double inputs must have integer values in the range of ASSUMEDTYPE.
 
>> bitxor(-10,-20)
Error using bitxor
Double inputs must have integer values in the range of ASSUMEDTYPE.


In Octave,


>> bitxor(-10,20)
ans =  20
>> bitxor(-10,-20)
ans = 0


So, it's not producing error, warning for negative inputs neither the result
is correct. 
Most importantly,help bitxor says,


-- bitxor (X, Y)
     Return the bitwise XOR of non-negative integers X and Y.


So, according to the help it should throw error for negative inputs.
