dig, libsocks5_sh & libpthread problem

[Andrew N. Below]

 Hello.

  I have to use socks5 server for outgoing connections
from office LAN. After updating to FreeBSD 5.4-RELEASE-p6
dig stops working via runsocks:

defbsd# runsocks dig
Bus error (core dumped)

defbsd# uname -sr
FreeBSD 5.4-RELEASE-p6

in logs:

 dig without runsocks works fine.

 runsocks is from socks5-1.0.11_3 port (/usr/ports/net/socks5).

 dig version is 9.3.1.

 FreeBSD has been cvsup'ed from 5.2.1 to 5.4-RELEASE-p6.
