Hi, When I compile my program that uses synchronous ssl::stream methods read_some and write_some, the compiler complains about ambigious binds. I believe this is a bug in the boost.asio library. My code compiled and run fine on boost_1_36_0 in windows environment, but not with boost_1_37_0 or boost_1_38_0 on solaris SPARC 10 environment? Boost compiles fine without any errors on solaris, so I believe this is a new boost.asio bug that has been introduced in the newest two releases. I tried to confirm this by building boost_1_36_0 on my solaris machine, but could not get it to compile without errors.
