php PCRE fail silently


I'm using the 1.4.8 Version and I got a small issue with php 5.4.41:

The PCRE stuff do not work, like preg_match() for exemple, they return an array of nothing. I confirmed that it's not my code as available tldextract.php (easy to find on google) return an array of nothing too.

According to the PHP doc, PCRE is enabled automaticaly at compile time using his own bundled libs so, it shoud just work.

Note, I did have the same issue with 1.4.7 too.

Someone have the same issue or a fix?
