Bug description: PHP crashes with invalid argument for DateTimeZone
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.
