I helped debug the issue for BoingBoing regarding exif_read_data() causing a segfault. 
This was on RHEL 6 PHP 5.4

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.
