I don't see any evidence that the libstdc++ in CentOS 7 ever had version definitions for CXXABI_1.3.8 or GLIBCXX_3.4.20. Both seem to only go up to CXXABI_1.3.7 and GLIBCXX_3.4.19, at least with the libstdc++ package. Perhaps you built your binaries on a system with newer version definitions? -- Jonathan Billings <billings at negate.org>
