Display problem

Hi --
I'm not sure if this is a bug, but it seems that if I can print something I should be able to display it. Thus if in the command area of the source window I have

l(3)@5

where l is a Fortran 77 integer array, and I hit the print button, I get

(gdb) print l(3)@5
$11 = (0, 1, 1108542220, 1107781925, 1)

But if I hit the display button, I get

(gdb) graph display l(3)@5
1: Invalid expression
Disabling display 1 to avoid infinite recursion.
(gdb) 1: Invalid expression
Disabling display 1 to avoid infinite recursion.

I wouldn't characterize this as serious, but it would be nice to be able to display a specific part of an array.

I tried to install a later rpm of ddd, but gave up in the usual rpm dependency hell.

Thanks for making ddd available; I don't know what I'd do without it!
       Fred
