I don't have time to look into this further today (or likely this week), but valgrind on a current 5.3 build shows a loss record demonstrating this: ==19168== 130,800 (11,200 direct, 119,600 indirect) bytes in 100 blocks are definitely lost in loss record 28 of 28 ==19168== at 0x4C27480: calloc (vg_replace_malloc.c:467) ==19168== by 0x471A5F: timelib_tzinfo_ctor (timelib.c:108) ==19168== by 0x471317: timelib_parse_tzfile (parse_tz.c:318) ==19168== by 0x442F99: timelib_get_zone (parse_date.re:807) ==19168== by 0x444520: scan (parse_date.re:1641) ==19168== by 0x46ED0E: timelib_strtotime (parse_date.re:1795) ==19168== by 0x435879: zif_strtotime (php_date.c:1427) ==19168== by 0x9E5022: execute_internal (zend_execute.c:1261) ==19168== by 0xBEA2D38: xdebug_execute_internal (xdebug.c:1335) ==19168== by 0x9E6057: zend_do_fcall_common_helper_SPEC (zend_vm_execute.h:318) ==19168== by 0x9EA9A7: ZEND_DO_FCALL_SPEC_CONST_HANDLER (zend_vm_execute.h:1606) ==19168== by 0x9E53E1: execute (zend_vm_execute.h:107) Previous Comments: ------------------------------------------------------------------------ [2010-12-08 21:05:59] jsheridan at tenable dot com This was found on a 5.3.2 system but verified against a fresh built 5.3.3 with no additions. ------------------------------------------------------------------------ [2010-12-08 21:04:11] jsheridan at tenable dot com Description: ------------ strtotime calls with a timezone embedded function correctly but continually use up memory. In a daemon program this becomes quickly fatal. Test script: --------------- <?php while (true) { strtotime('Monday 00:00 Europe/Paris'); // Memory leak } ?> <?php while (true) { date_default_timezone_set("Europe/Paris"); strtotime('Monday 00:00'); // No memory leak } ?> Expected result: ---------------- Memory usage should remain stable. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53502&edit=1
