Hope 3 hours of my work will help someone.
My crawler crashes php (windows7 and php 5.6, apache module) on some sites. The reason was in class PHPCrawlerLinkFinder->findLinksInHTMLChunk() in preg_match_all function (in version 083 it is line 178). The related bug https://bugs.php.net/bug.php?id=61744 helped me to solve issue - I just increase pcre.backtrack_limit and pcre.recursion_limit in php.ini. After it - everything works perfect.
Best regards!
