Description:

Hi,

When I try to preg_replace a 2654 long string, I get a PREG_BACKTRACK_LIMIT_ERROR

It's strange because as shown, the PHP pcre.backtrack_limit is set as the default 100000 limit.

Why does it hits the limit with a short string like this ?

Thanks

Reproduce code:

<http://pastebin.com/fa42d78d>

Expected result:
----------------
100000
2653
2653


Actual result:
--------------
100000
2653
Error: PREG_BACKTRACK_LIMIT_ERROR
