Fix is coming. ------------------------------------------------------------------------ [2007-01-09 14:40:23] [EMAIL PROTECTED] According to a few exif tools this image is either invalid or has corrupted exif information. ------------------------------------------------------------------------ [2007-01-09 11:44:00] [EMAIL PROTECTED] Marcus, I've fixed the segfault, but the result EXIF data is still b0rked, please see if we can do anything about it. ------------------------------------------------------------------------ [2007-01-09 11:07:03] camka at email dot ee Description: ------------ PHP dies on certain files format while reading exif data with exif_read_date because of some maximum directory nesting level reached. The function should return FALSE and let the program flow further. Otherwice misformated image processing may kill script and break the program logic. Even if i suppress warnings with @ sign, i still cannot manage to let the program go further after unsuccessfull reading exif data. broken file: http://www.hot.ee/camka/orig.phpJCN9Ir.jpg Tried with 5.1.6, 5.2.0 and latest snapshot of 5.2.1. P.S. All editors successfully show EXIF data for current file, so maybe it's not misformatted exif data but exif extension cannot process some newer exif formats? Reproduce code: --------------- <? $z = exif_read_data('orig.phpJCN9Ir.jpg', 'FILE,COMPUTED,IFD0,EXIF', true, false); var_dump($z); Expected result: ---------------- [...Errors (see below)...] FALSE Actual result: -------------- $ php exif.php PHP Warning: exif_read_data(orig.phpJCN9Ir.jpg): Illegal IFD size: x04F6 + 2 + xFFF1*12 = xC0442 > x16BF in exif.php on line 2 PHP Warning:
