Release candidate files for 1.65.0 are available at http://boost.cowic.de/rc/

As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy.

This helps ensure the candidates build OK before we push them out to SourceForge.>> The files (and associated md5s) are: MD5 (boost_1_56_0_rc1.7z) = 0ac22b92b24209286d48e4c41925cd9f MD5 (boost_1_56_0_rc1.tar.bz2) = 5b5bfa99244b1ac5737323decceb19c2 MD5 (boost_1_56_0_rc1.tar.gz) = 2047cdd4e09cda34e7f10fec0f821175 MD5 (boost_1_56_0_rc1.zip) = 0c544f6acc85550b15cdc9221f2ac0c9

I also see compilation failures with gcc 4.6 in C++11 mode:

I think the problem is in Boost.Thread, boost/thread/detail/invoke.hpp. I emailed Vicente, no response so far. I'll try to come up with a patch.
