The offending file is needed. could you upload them somewhere and link it? ------------------------------------------------------------------------ [2015-02-10 00:04:29] stephane dot boisvert at automattic dot com I helped debug the issue for BoingBoing regarding exif_read_data() causing a segfault. This was on RHEL 6 PHP 5.4 ------------------------------------------------------------------------ [2015-02-09 22:09:11] ken at boingboing dot net We're experiencing the same issue. Any attempt to import this post into wordpress generated the same issue when it calles exif_read_date (for reference, wp-admin/includes/image.php, line 339): $exif = @exif_read_data( $file ); Removing the EXIF data eliminates the issue. ------------------------------------------------------------------------ [2014-12-30 10:41:51] php-bugs at lists dot php dot net No feedback was provided.

After burning a handful of hours on this, I've worked around by nuking the VPS, and installing a 64-bit 12.04 Ubuntu. This failed to repro segfault on this, or any of the images attached above (yay). ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
