I've been getting reports in the field about sporadic SSL crashes in our product (Linux version). After using a stress test for several hours, I got it to crash in asio 1.41. I then tried it in 1.44 and got the same crash on windows. It appears to be crashing in openssl_operator.hpp:158 The session_ object is definitely corrupt: session_ 0x000000022120ac30 {version=-17891602 type=-17891602 method=0xfeeefeeefeeefeee ...} version -17891602 int type -17891602 int + method 0xfeeefeeefeeefeee {version=??? ssl_new=??? + rbio 0xfeeefeeefeeefeee {method=??? callback=??? + wbio 0xfeeefeeefeeefeee {method=??? callback=??? + bbio 0xfeeefeeefeeefeee {method=??? callback=??? The callstack is this: NwConcentrator.exe!boost::asio::ssl::detail::openssl_operation< boost::asio::basic_stream_socket< boost::asio::ip::tcp,boost::asio::stream_socket_service< boost::asio::ip::tcp>> >::start() NwConcentrator.exe!boost::_mfi::mf0 ::operator() (boost::asio::ssl::detail::openssl_operation< boost::asio::basic_stream_socket< boost::asio::ip::tcp,boost::asio::stream_socket_service< boost::asio::ip::tcp>> > * p=0x00000002136cf440) Line 50 C++ Does 1.45 have a fix for this? I looked over the release notes but didn't see anything about SSL fixes. This crash is occurring on both Fedora/CentOS/Windows builds of boost asio 1.41 and 1.44. Thanks, Scott
