"gdb: Symbol `emacs_ctlx_keymap' has different size..."

Whenever I start gdb, I get the warning:

  % gdb --version
  gdb: Symbol `emacs_ctlx_keymap' has different size in shared object, consider re-linking

My system is

  % uname -ar
  Linux yow 2.4.18 #1 Sun Apr 4 17:45:51 EDT 2004 i686 unknown

mostly stable distribution (including my gdb and emacs).  In case it
matters, my emacs is

  % emacs --version

If this is not a bug in the gdb package, what must I do to get rid of
this error message?

Thanks,
