--SKIPIF--
<?php
if (!extension_loaded('mbstring')) die('skip mbstring extension not available');
if (!function_exists('mb_ereg_replace')) die('skip mb_ereg_replace() not available');

<?php

// This behavior is broken, but kept for BC reasons
var_dump(mb_ereg_replace('(%)', '\\\1', 'a%c'));
// For clarity, the above line is equivalent to:
var_dump(mb_ereg_replace('(%)', '\\\\1', 'a%c'));

?>
--EXPECT--
string(4) "a\%c"
