--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- You didn't say you are using devtoolset. That uses a different linking model, so it's correct that your program is linked to the gcc-4 libraries. Devtoolset is not supported by the upstream project, you should report this to the CentOS or Red Hat bug tracker and we'll help there. It's possible that <system_error> is one of the components that isn't fully usable with devtoolset, due to the limitations of the gcc-4 libraries. I'll look into it.
