BOOST_NO_EXCEPTIONS can be used to simply disable exception handling in boost not necessarily to flag that exception handling is disabled at the compiler level: http://www.boost.org/doc/libs/1_36_0/libs/utility/throw_exception.html BOOST_NO_EXCEPTION can be used to supply a custom exception handler. Wrapping the try block on line 136 on system/error_code.cpp with #ifndef BOOST_NO_EXCEPTIONS fixes this. See ticket #2098" Bugs reopened To Be Determined system Boost 1.51.0 Problem viboes
