Subject: [asio] has anybody enabled SSL in a large project?

yes after two day debugging looking for fixes and some hot fixes it begin to

get lastest version of asio asap or search google for changes in ssl support

it seems that problem with buffer sizes try to change
::BIO_new_bio_pair(&int_bio, 3*8192, &impl->ext_bio, 3*8192);

that's not a solution in my opinion
