Eh, you're right.  It's broken.

(gdb) record
(gdb) b 6
Breakpoint 2 at 0x8048352: file nop.c, line 6.
(gdb) b 7
Breakpoint 3 at 0x8048353: file nop.c, line 7.
(gdb) n

Breakpoint 3, main () at nop.c:7
7               asm ("nop");
(gdb) n
8               asm ("nop");
(gdb)
9               asm ("nop");
(gdb) n
10      }
(gdb) rc
Continuing.

Breakpoint 3, main () at nop.c:7
7               asm ("nop");
(gdb) rn

No more reverse-execution history.
main () at nop.c:6
6               asm ("nop");
(gdb) n

Breakpoint 2, main () at nop.c:6
6               asm ("nop");
(gdb)
8               asm ("nop");
(gdb)
9               asm ("nop");
(gdb)
