Bug description: preg_match fails if strlen >= 1630
Description:
------------
preg_match() with regexp to test for valid UTF-8 sequence - fails and
causes the error message:
'Could not open input file: <name of script>.php'
IF the subject string passed to preg_match() is longer than 1629
characters. (Or in this case the size of the file 'zzz' which contains
ASCII)
There was no such limitation in preg_match() in the previous version of
PHP (5.1.2)
Reproduce code:
---------------
$str = file_get_contents('zzz');
echo "Loaded file...\n";
$result =
preg_match('/^([\x00-\x7f]|[\xc2-\xdf][\x80-\xbf]|\xe0[\xa0-\xbf][\x80-\xbf]|'
.
'[\xe1-\xec][\x80-\xbf]{2}|\xed[\x80-\x9f][\x80-\xbf]|[\xee-\xef][\x80-\xbf]{2}|'
.
'\xf0[\x90-\xbf][\x80-\xbf]{2}|[\xf1-\xf3][\x80-\xbf]{3}|\xf4[\x80-\x8f][\x80-\xbf]{2})*$/S',
$str) === 1;
echo "Back from preg_match()\n";
var_export($result);
echo "\n";
Expected result:
----------------
Loaded file...
Back from preg_match()
true
Actual result:
--------------
Loaded file...
Could not open input file: u8.php
