Re-opening (reclassified & updated summary)
The problem isn't in ext/datetime.
All exception thrown via zend_parse_parameters() are caught by a user
defined error handler:
<?php
function err() {
echo "User defined errorhandler triggered\n";
}
set_error_handler("err");
$obj = new ArrayObject(null, "foobar");
var_dump($obj);'
?>
User defined errorhandler triggered
object(ArrayObject)#1 (0) {
}

This bug has been fixed in CVS.
Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
Thank you for the report, and for helping us make PHP better.

Description:
------------
If no custom error-handler is defined via set_error_handler() it works
like I would expect it. If I pass an invalid argument to the constructor
of DateTimeZone an exception is thrown with "Unknown or bad timezone
(...)".
But as soon as I define a custom error-handler the behavior changes.
The creation of DateTimeZone causes no problem. But if I pass the
created object to DateTime PHP crashes.
Reproduce code:
---------------
<?php
function handleError() {}
set_error_handler('handleError');
$t = new DateTimeZone('something');
$d = new DateTime('now',$t);
?>
Expected result:
----------------
Of course, PHP should not crash but trigger an error / throw an
exception :)
Actual result:
--------------
I've tried to get the backtrace. I don't know if I've done this
correctly. The howto linked on this page doesn't work for me. I've done
the following:
$ gdb /usr/bin/php5
$(gdb) run myfile.php
$(gdb) bt
The result is:
Program received signal SIGSEGV, Segmentation fault.
#0 0x080dff87 in timelib_tzinfo_clone ()
#1 0x080c5e63 in zif_date_timezone_set ()
