--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Andreas Schwab from comment #1) > You always need to use the libstdc++ that is bundled with the compiler. Actually that is true but that does not make this bug a valid bug. What is mentioned is c++11 abi breaks between 4.9 and 5. So this bug is still invalid but a slightly different reason. From now (5), gcc will no longer break the abi.
