I've been trying to make a habit of watching new bug reports and today this
one came in: https://bugs.php.net/bug.php?id=67238 This is a
pretty severe
regression that should be fixed upstream. Felipe suggested I post it here.

It's small enough I'll post the bug report here too:

Description:
------------
There is bug causing min/max quantifiers to not work in ungreedy mode
in PCRE 8.34.
http://bugs.exim.org/show_bug.cgi?id=1451

Bug is fixed in PCRE 8.35.

Test script:
---------------
echo preg_match('/a{1,3}b/U', 'ab');

Expected result:
----------------
1

Actual result:
--------------
0
