#50845 [NEW]: exif_read_data returns corrupted exif headers

From: zerkella at i dot ua Operating system: windows, linux PHP version: 5.3.1 PHP Bug Type: EXIF related Bug description: exif_read_data returns corrupted exif headers Description: ------------ exif_read_data returns bad values for headers for some photos. Headers look like corrupted during extraction from file - like they were mixed with and overwritten by other exif headers. I tried to check Exif headers for same photos with XnView - it shows them nicely. So the problem is somewhere in php.
