I note that your code has    diff[j,i]   while your prose has   diff[i,j].
That is, the order of subscripts is reversed.  This may be a typographical
error in your email, or a real error in your code.  You should check
that out.

Otherwise, if you still think there is a bug, please construct a small
but COMPLETE awk program with a small input data set that illustrates
the problem, and send it to me.  You should also indicate what version of
gawk you are using, how it was compiled, what system you have, and so on.

Thanks,
