[Bug debug/30629] New: [Regression:4.3/4.2] -g causes undefined references

["mueller at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Consider this testcase: 

=== Cut ===
static int hacky_auxmaps[20000];
static signed int auxmap_used = 0;
static int *auxmap = &hacky_auxmaps[0];

static void
mc_pre_reg_read ( unsigned  size)
{
  vgPlain_message ("memcheck: auxmaps: %d auxmap entries in use", auxmap_used);
}
=== Cut ===

compiling it with -O2 -g results in an undefined reference to "hacky_auxmaps".
just compiling with -O2 or with -O0 fixes it.
