Segmentation fault when enabling Optimize CSS Code

    I just installed this plugin on my local test box and when I enable the optimize CSS Code, I am getting an internal server 500 error. I checked through the Support page and confirmed I had my AllowOverride All.
    I installed the plugin on my staging site Remote Host) and got the same thing when enabling Optimize CSS.
    Checked the Apache logs on my local server and found that when I enable it, I get [core:notice] [pid:xxxx] AH00051: child pid xxxx exit signal Segmentation Fault (11).
    My local PHP version is 5.5.9-1. Zend engine 2.5.0 Zend OPcache 7.0.3. These should be pretty close to the latest version. My WP site is 4.4.3.
    I am using WooCommerce and Divi and I don’t have any other optimization plugins installed.
    Again, if I just disable Optimize CSS everything works again.

    Hi ryangcad;
    That’s PCRE (perl compatible regular expressions) crashing PHP, probably due to the the amount of CSS OR due to something … funky in the CSS. As per the FAQ;

    In some rare cases the CSS minification component currently used by Autoptimize crashes due to a lack of resources (see detailed technical explanation here). You can in that case either disable CSS optimization, try to exclude specific CSS from being aggregated or activate the legacy minifiers which don’t have that problem. The latter can be accomplished by adding this to your wp-config.php:

    define("AUTOPTIMIZE_LEGACY_MINIFIERS","true");

    The “legacy minifiers” will remain in Autoptimize “for ever” and changes to wp-config.php are not affected by core-, theme- or plugin-upgrades so you should be good to go.

    If that does not work, you can try selectively excluding one or more CSS-files from optimization.

    hope this helps,
    frank

    Thanks so much for the reply. I added the legacy minifyers and that seems to have corrected the issue.
    One thing that is interesting is that I have tried to minify my style.css files in the past for my theme and have always had formatting issues but when doing it through Autoptimize, it is working great.
