Description:
------------
Thumbnails from my Canon 100D camera can no longer be extracted from the EXIF data.

The test script will only output an error when using PHP 5.6.24 or 5.6.25:
With PHP 5.6.23 it is working (as it always has been for me) and EXIF data including thumbnail is being output.


Test script:
---------------
print_r( exif_read_data( "/tmp/IMG_5888_small.JPG", "THUMBNAIL" ) );

Expected result:
----------------
Output EXIF data with no error

Actual result:
--------------
This warning is being output and no EXIF data (if requiring the thumbnail or using another function to extract the thumbnail):

Warning: exif_read_data(IMG_5888_small.JPG): IFD data bad offset: 0xFFFFFD32 length 0x1EC2 in /tmp/exif.php on line 2
