Comment 12 Pavel Malyshev 2014-10-20 16:44:40 UTC
The issue went away after an upgrade to Yii 1.1.15.
The failure seems to be caused by some autoload configuration magic.

The code of Yii-1.1.12 (yii/framework/test/CTestCase.php):
--------------------------------
require_once('PHPUnit/Util/Filesystem.php'); // workaround for PHPUnit <= 3.6.11
require_once('PHPUnit/Autoload.php');
spl_autoload_unregister('phpunit_autoload');
Yii::registerAutoloader('phpunit_autoload');
--------------------------------
The last line caused the segfault.


Yii::registerAutoloader() is:
--------------------------------
public static function registerAutoloader($callback, $append=false)
{
...
                        spl_autoload_unregister(array('YiiBase','autoload'));
                        spl_autoload_register($callback);
                        spl_autoload_register(array('YiiBase','autoload'));
...
}
--------------------------------
It used to segfault at the 'spl_autoload_register($callback);'




The new code:
--------------------------------
require_once('PHPUnit/Runner/Version.php');
require_once('PHPUnit/Util/Filesystem.php'); // workaround for PHPUnit <= 3.6.11

spl_autoload_unregister(array('YiiBase','autoload'));
require_once('PHPUnit/Autoload.php');
spl_autoload_register(array('YiiBase','autoload')); // put yii's autoloader at the end

if (in_array('phpunit_autoload', spl_autoload_functions())) { // PHPUnit >= 3.7 'phpunit_autoload' was obsoleted
    spl_autoload_unregister('phpunit_autoload');
    Yii::registerAutoloader('phpunit_autoload');
}
--------------------------------


So the most likely PHP tried to signal that there is no 'phpunit_autoload' when 
Yii::registerAutoloader() tried to register it.

Since there is a fix in framework I believe that priority of this bug should be low, but PHP should not segfault anyway.

Comment 13 Fedora End Of Life 2015-05-29 13:07:50 UTC
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. 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bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora  'version'
of '20'.

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.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 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, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

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.

Comment 14 Fedora End Of Life 2015-06-29 22:59:14 UTC
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
