This causes gdb to crash in lookup_symtab.

    if (full_path != NULL)
      {
	const char *fp = symtab_to_fullname (s);
	if (FILENAME_CMP (full_path, fp) == 0)
	  {
	    return s;
	  }
      }

    if (real_path != NULL)
      {
	char *rp = gdb_realpath (symtab_to_fullname (s));
        make_cleanup (xfree, rp);
	if (FILENAME_CMP (real_path, rp) == 0)
	  {
	    return s;
	  }
      }

Neither of these places expect symtab_to_fullname to return NULL.
