System: Linux sykes 2.4.18-SMP #1 SMP Sat Apr 13 18:56:25 UTC 2002 ia64 unknown

>Description:
A reference to a label is generated that is never defined.  This happens
only when compiling with -g.  Without -g the object that references the
omitted label is optimized out completely, since it is actually unused
anyway.
>How-To-Repeat:
$ cat const.cc
static const int foo[] = { 0 };
static const int * const bar[] = { foo };
$ gcc -O -g -c const.cc
$ nm -u const.o
foo
