tiff2ps (from 3.7.0) is failing on on my Darwin (Mac OS/X) system. It looks like the problem is in setupPageState() where the wrong value is returned from TIFFGetField(tif, TIFFTAG_XRESOLUTION, &xres)

xres is a double, but in TIFFGetField(), which in turn calls _TIFFVGetField, we eventually get to this line in tif_dir.c, where the pointer is being treated as a float.:

        case TIFFTAG_XRESOLUTION:
            *va_arg(ap, float*) = td->td_xresolution;
            break;

I'm not sure it's the best fix, but this works for me:
