I don't know too much about GDB's Fortran support, but the GDB
`artificial array' feature should work with Fortran as well.  Simply try

(gdb) print ia(3) @ 5

If this doesn't work, try C syntax (and C array indexes *sigh*)

(gdb) set language c
(gdb) print ia[2] @ 5

For more details, see `artificial arrays' in the GDB manual.
