Warning with HHVM

Does anyone has an answer for that problem?
Here is a stacktrace:

[Mon Jul 14 19:29:47 2014] [hphp] [1725:7fcaf33ff700:5:000001] [] \nWarning: Parameter 1 to W3_Plugin_TotalCache::ob_callback() expected to be a reference, value given in /var/www/xn--jr-wstensachsen-2vb.de/wp-includes/functions.php on line 2935

I also see the same in my HHVM error log.

HipHop VM 3.2.0 (rel)
nginx version: nginx/1.7.5
built by gcc 4.8.2 (Ubuntu 4.8.2-19ubuntu1)

Wordress 4.0
W3TC Version 0.9.4

Please email us.

Same here and HHVM is crashing. ??

See reported issue at https://github.com/facebook/hhvm/issues/3876

So we can get this fixed.

Thanks for bringing this to our attention, we took a look and verified the issue being reported. A fix will be in the forthcoming release.

Thanks! ??

Same issue here. Nginx & PHP5-FPM works flawless. When I use HHVM 3.2.0 I get the following error:

Warning: Parameter 1 to W3_Plugin_TotalCache::ob_callback() expected to be a reference, value given in /wp-includes/functions.php on line 3092

@Till Krüss: as mentioned above, this has been addressed in the next release.

Awesome, thanks!

Even we are having the same issue.

Waiting for next W3 Total Cache Plugin release. Thanks for the update Willie ??

@willie Jackson I have update W3 total plugin, but again we are getting same warning messages.
Has these issues been fixed?
