Description:
------------
there is some bug in preg_match only in php 5

preg_match("/^$login_/,$sth) will always be true

preg_match("/^$login/,$sth) is ok. diffrence is _ after $login. You cant use it :/

if before matching $login = "$login_"; everytjing will be ok.

ok. thats probably not bug but diffrence. you got to
preg_match("/^$login\_/,$sth)

anyway by making such diffrences you make all aplications writen to 4.x incompatibile.
