Occasional segfault with Joomla 3.4.6

[ghost]

This is what i get in the stacktrace .log in tmp folder when it happens (I'm using latest hhvm on ubuntu apt repo):

PHP Stacktrace:

#0  JDate->__construct(now) called at [/omissis/libraries/joomla/log/entry.php:96]
#1  JLogEntry->__construct(JError::setErrorHandling() is deprecated., 16, deprecated, ) called at [/omissis/libraries/joomla/log/log.php:148]
#2  JLog::add(JError::setErrorHandling() is deprecated., 16, deprecated) called at [/omissis/libraries/legacy/error/error.php:350]
#3  JError::setErrorHandling(8, message) called at [/omissis/includes/framework.php:18]
#4  include(/omissis/includes/framework.php) called at [/omissis/index.php:36]

this is the JData constructor method signature:

/**
     * Constructor.
     *
     * @param   string  $date  String in a format accepted by strtotime(), defaults to "now".
     * @param   mixed   $tz    Time zone to be used for the date. Might be a string or a DateTimeZone object.
     *
     * @since   11.1
     */
    public function __construct($date = 'now', $tz = null)
    {

this is how is getting invoked at entry.php:96:

$this->date = new JDate($date ? $date : 'now');

Can I provide more data to help you debbugging it? let me know

I've also had one of our servers report a similar issue with this (Wordpress however):

Let me know if you would like me to try and replicate in a debug version in order to get a full backtrace?

Might be fixed with 47cff55

Can you reproduce with a nightly build?

[davidxdunn]

Tested using nightly debug and unable to replicate the crash :)

@CreativeProgramming Are you still seeing the segfault with HHVM and Joomla? ( same as #5520 )

I've been working on and off at getting the php unit tests for Joomla working ( see joomla/joomla-cms#10220 ), right now we are faced with some HHVM issues like memory_get_peak_usage() causing a Fatal error: request has exceeded memory limit related to the HHVM implementation of ini_restore plus a few (fairly new) unrelated compiler bugs found by @aorenste ( see #7035 ) and running under hhvm's php 7 mode there is an issue with "type annotations on internal functions" ( see #7198 )

[paulbiss]

Going to close this for now as there are more specific issues open for the known problems. If anyone gets a repro please let me know and I will reopen.

@CreativeProgramming Joomla staging now passes unit tests on HHVM 3.15.3 and the pre-release 3.7.0 Alpha 1 should be testable for developer site preview with HHVM 3.15.3+
