Bug description: Inconsistent behaviour by same type of regex
Description:
------------
Min/max quantifiers '{}' in preg_match() don't seem to match more than
765 characters.
Reproduce code:
---------------
// $matches[1] contains the first 765 characters of the string $sample:
preg_match("/^(.{765}).*/", $sample, $matches);
// doesn't match anything:
preg_match("/^(.{766}).*/", $sample, $matches);
// Values from {0} to {765} appear to work fine. 766 onwards, nothing
gets matched.
Expected result:
----------------
I expect the same type of behaviour to happen in both cases.
I realize that preg_match() isn't really necessary to match the first x
characters in a string, but this problem was affecting a more complex
regex I was doing. The "matching the first x chars" example was trying
to isolate where the problem was occurring.
