Attempt to solve issue #10 #24

Closed dmenendez-gruposantander closed 4 years ago

boost::current_exception uses C++11 std::current_exception when supported to transport exceptions without the need to wrap in boost::enable_current_exception.

gcc errors: some versions are complaining with ./boost/exception/detail/exception_ptr.hpp:436:90: error: cannot allocate an object of abstract type boost::exception_detail::clone_base but the offending code does not in fact instantiate clone_base!

exception_detail::clone_base const& base {
     boost::enable_current_exception(std::current_exception())};
return exception_ptr(shared_ptr<exception_detail::clone_base const>(base.clone()));

I'm declaring base as a reference to the base class to bind the temporary of whatever class is returned from boost::enable_current_exception() Maybe I should just be using auto?

clang errors: I don't see how the reported error is even remotely related to my changes...

bin.v2/libs/exception/test/cloning_test.test/clang-linux-3.6.2/debug/link-static/threading-multi/visibility-hidden/cloning_test.o: In function `void test_std_exception_what<std::ios_base::failure>()':
/home/travis/build/boostorg/boost-root/libs/exception/test/cloning_test.cpp:168: undefined reference to `std::ios_base::failure::failure(char const*, std::error_code const&)'

Clang errors are gone after adding dist: trusty to the Travis config.

However the gcc errors for older versions of gcc are still there! :(
