 New Comment:

PCRE and ereg_* have different syntaxes. So wrapping ereg to pcre will
break most regexes.

For unicode aware regexps use PCRE. The old ereg stuff should be
provided as wrapper functions which uses PCRE underneath though.

This is expected, the code isn't prepared to works with unicode
strings.
Actually it only use REG_EXTENDED with binary strings, and convert the
unicode string to normal string.

Description:
------------
expressions that work in older versions fail on PHP6
unicode.semantics=on

Compared 5.2-dev, 5.3-dev and 6.0-dev snapshots

Reproduce code:
---------------
$line = "* 469 EXISTS\r\n";
if (ereg("[^ ]+ +([^ ]+) +EXISTS", $line, $match)) {
    var_dump($match[1]);
} else {
    var_dump(false);
}

$line = "* 469 FETCH (UID 508 BODY[1]<0> {154}\r\n";
if (ereg('\\{([^\\}]*)\\}', $line, $match)) {
    var_dump($match[1]);
} else {
    var_dump(false);
}

Expected result:
----------------
string(3) "469"
string(3) "154"

Actual result:
--------------
bool(false)

Warning: ereg(): REG_BADRPT in
/home/tomas/testbeds/test/php60/bin/ereg.php on line 10
bool(false)
