------- Comment #7 from hjl at lucon dot org  2008-01-07 04:57 -------
gfc_undo_symbols has

 for (p = changed_syms; p; p = q) 
    {    
      q = p->tlink;

      if (p->new)
        {    
          /* Symbol was new.  */
          delete_symtree (&p->ns->sym_root, p->name);

          p->refs--;
          if (p->refs < 0) 
            gfc_internal_error ("gfc_undo_symbols(): Negative refs");
          if (p->refs == 0)
            gfc_free_symbol (p);
          continue;
        }

"P" is freed. But it still accessible by resolve_common_vars somehow.
