Hi everyone, version 1.69 of boost.test broke the line *runtime_config::get(runtime_config::btrt_log_level)* It works with static linking, however it breaks on dynamic linking. Error message is *boost::runtime::arg_type_mismatch: Access with invalid type for argument corresponding to parameter log_level* In particular the following program fails: * #define BOOST_TEST_MODULE example #define BOOST_TEST_DYN_LINK #include <iostream> #include #include BOOST_AUTO_TEST_CASE(failDyn) { using namespace boost::unit_test; std::cout << runtime_config::get( runtime_config::btrt_log_level ) << std::endl; }* if boost.test is linked dynamically. Best regards, David Sommer
