I am running c++filt on ubuntu 18.04, it can demangle some names but failed other names:
$ c++filt _ZN5boost4asio6detail9scheduler3runERNS_6system10error_codeE+0x83 _ZN5boost4asio6detail9scheduler3runERNS_6system10error_codeE+0x83 The same name can be demangled in http://demangler.com/: boost::asio::detail::scheduler::run(boost::system::error_code&) 0x83 What I could be missing why the c++filt could not demangle it? $ c++filt --version GNU c++filt (GNU Binutils for Ubuntu) 2.30 Thank you. Kind regards, jupiter
