[OpenSIPS-Users] problem with pv string concatonation

[Bogdan-Andrei Iancu]

Hi Brett,

just tried the following piece of script:

    xlog("1---------------------$rU\n");
    $avp(s:lnp_prefix) = "buruburu";
    $rU =  $avp(s:lnp_prefix) + $rU;
    xlog("2---------------------$rU\n");
    sl_send_reply("404","Get lost");
    exit;

and got:

Which looks ok to me....testing the svn head..
