Thanks. So are you saying that gcc's mangling
_ZN5folly12addBenchmarkIUliE_EENSt9enable_ifIXeqsrN5boost14function_types14function_arityIDTadsrT_clEEE5valueLi2EEvE4typeEPKcSC_OS6_
instead of
_ZN5folly12addBenchmarkIUliE_EENSt9enable_ifIXeqsrN5boost14function_types14function_arityIDTadsrT_onclEEE5valueLi2EEvE4typeEPKcSC_OS6_
may be a wrong code bug?
