Yes, 2.0.5b1 (which on some distros is equivalent to 2.0.4-4) and iperf 3.x - see Jon Dugan's posts from a couple of weeks ago on this list and http://code.google.com/p/iperf/ FWIW, I can't replicate your original issue using either iperf-2.0.4/5 or iperf-3.0a1, but you've only shared part of your setup - how did you invoke the iperf server instance? > or non-C++ Linux version available ?
