Test script: --------------- <?php $a = new DateInterval("2008-05-11T15:30:00Z/2007-03-01T13:00:00Z"); var_dump($a); ?> Expected result: ---------------- At a minimum, "Not crashing". Ideally, a DateInterval object with a negative duration, but I don't know of ISO-8601 allows those. Actual result: -------------- (gdb) r -r '$a = new DateInterval("2008-05-11T15:30:00Z/2007-03-01T13:00:00Z"); var_dump($a);' Program received signal SIGSEGV, Segmentation fault. 0x0000000000420faf in date_object_get_properties_interval (object=<value optimized out>) at /home/joey/src/php/trunk/ext/date/php_date.c:2242 2242 PHP_DATE_INTERVAL_ADD_PROPERTY("y", y); "bt full" output available at http://codepad.org/on7ZS6Qd ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52808&edit=1
