[Bug fortran/21125] New: gfortran - bus error printing warning message

[dir at lanl dot gov]

I get a bus error when I try to compile this program. If you look at the trace
back, translate_common was making a call to gfc_warning with this statement -

	      gfc_warning ("Padding of %d bytes required before '%s' in "
			   "COMMON '%s' at %L", offset, s->sym->name,
			   common->name, &common->where);
	    }

offset is declared by -

  HOST_WIDE_INT offset;

on the Macintosh, the program is crashing because HOST_WIDE_INT is 8 bytes and
the %d format is only skipping 4 bytes throwing off the address for the later
arguments. Cast statements are needed on the calls with the "long int" to
gfc_warning or a new "%ld" option needs to be added to gfc_warning.
