W3TC Bug & PHP 7 compatibility

Frederick,

Thanks for W3TC!

With PHP 7 I’m seeing many errors like the one below:
[error] [client X.X.X.X] FastCGI: server “/home/www/fastcgi.fcgi” stderr: PHP message: PHP Warning: Parameter 1 to W3_Plugin_TotalCache::ob_callback() expected to be a reference, value given in /home/www/site/wp-includes/functions.php on line 3553

Is there a reason to not make the below change to line 512 of lib/W3/Plugin/TotalCache.php?
– function ob_callback(&$buffer) {
+ function ob_callback($buffer) {

It’s been suggested elsewhere, and seems to work wonderfully on 5.6 & 7.0x

Thanks!
