Description: ------------ Crash when using DateTimeZone object, previously returned by DateTime::getTimezone() This worked fine in PHP 5.2.5 Probably this is related to how DateTimeZone object is returned: This code returns different results in 5.2.5 and 5.2.6 $old_tz = $d->getTimezone(); $d->setTimezone(new DateTimeZone('UTC')); echo $old_tz->getName(); 5.2.6 returns 'UTC', while 5.2.5 returns 'Asia/Novosibirsk' (my current timezone). Having in mind how objects in PHP5 are returned, I can accept this, but this must be documented properly and shouldn't cause crash. Reproduce code: --------------- $d = new DateTime(); $old_tz = $d->getTimezone(); $d->setTimezone(new DateTimeZone('UTC')); // setDate() and setTime() may go here - just for this example to make some sense $d->setTimezone($old_tz); echo "Success"; Expected result: ---------------- Success Actual result: -------------- PHP interpreter crashes
Thanks for the report. I can see the bug, the reference to the timezone info is not duplicated/refcounted internally, so the $old_tz contains a stale pointer after the second setTimezone call and all bets are off from there on.
Patch submitted upstream http://article.gmane.org/gmane.comp.php.devel/51838
OK, this got merged to 5.2.x so will be there when 5.2.7 is out and makes it through to an update. Can you work around it in the meantime? I can do a build with the patch applied if that helps, but it won't be worth pushing an update just for this.
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
