I can't explain it, but here it is (rand was set to 'normal'):

-------------------------------------------------------------------------
octave:15> A=rand(floor(rand()*10-4),floor(rand()*10-4));norm(A),norm(A')
ans = 3.7211
ans = 3.7211
octave:16> A=rand(floor(rand()*10-4),floor(rand()*10-4));norm(A),norm(A')
