ext/exif/exif.c:
In exif_iif_add_value() , since the increment of value pointer is not
appropriately performed, when length is larger than 1, the elements
after 2nd are overwritten by 1st element.
ex) GPS.GPSLatitude
if the real value of GPSLatitude is "36/1 43859/1000 0/1",
$exif = exif_read_data('filename',0,true);
$lad = $exif["GPS"]["GPSLatitude"][0];
$lam = $exif["GPS"]["GPSLatitude"][1];
$las = $exif["GPS"]["GPSLatitude"][2];
"$lad,$lam,$las" has to be "36/1 43859/1000 0/1".
But, it is set to "36/1 36/1 36/1" in the present.
