Summary: plot2d(sum(1/i,i,1,n),[n,1,10]) produces stack overflow

Initial Comment:
Executing "plot2d(sum(1/i,i,1,n), [n,1,10])" fails 
with "Unrecoverable error: bind stack overflow".

Message:
I think the problem has gone. I have no problems to get the plot with
Maxima 5.19post.

Settting the status to pending and "works for me".

plot2d assumes (unless told otherwise) that the expression
to be plotted can be evaluated at any point within [1, 10].
However sum(1/i,i,1,n) is only well-defined for integer n.
Perhaps you meant 

L1 : makelist (n, n, 1, 10);
L2 : makelist (sum(1/i, i, 1, n), n, 1, 10);
L2 : L2, numer;
plot2d ([discrete, L1, L2]);

Although "plot2d(sum(1/i,i,1,n), [n,1,10]); isn't valid,
plot2d should try to do something smarter than stack
overflow in that case.
