info frame

[Nick Roberts <nickrob@snap.net.nz>]

'info frame' says that the frame is at a different address (0xbffff710)
to $fp (0xbffff708).  This wasn't the case with older versions e.g 5.2.1:

  nickrob/31  gdb myprog
  GNU gdb 5.2.1-2mdk (Mandrake Linux)
  Copyright 2002 Free Software Foundation, Inc.
  ...
  (gdb) inf frame
  Stack level 0, frame at 0xbffff728:
   eip = 0x80484a9 in main (myprog.c:47); saved eip 0x4006015a
   called by frame at 0xbffff768
   source language c.
   Arglist at 0xbffff728, args: argc=1, argv=0xbffff794
   Locals at 0xbffff728, Previous frame's sp is 0x0
   Saved registers:
    ebp at 0xbffff728, eip at 0xbffff72c
  (gdb) p $fp
  $1 = (void *) 0xbffff728

  nickrob/32 src/gdb/gdb myprog
  GNU gdb 6.4.50.20060405-cvs
  Copyright (C) 2006 Free Software Foundation, Inc.
  ...
  (gdb) info frame
  Stack level 0, frame at 0xbffff710:
   eip = 0x80484a9 in main (myprog.c:47); saved eip 0x4006015a
   source language c.
   Arglist at 0xbffff708, args: argc=1, argv=0xbffff774
   Locals at 0xbffff708, Previous frame's sp is 0xbffff710
   Saved registers:
    ebp at 0xbffff708, eip at 0xbffff70c
  (gdb) p $fp
  $1 = (void *) 0xbffff708

Can this be right?
