It probably doesn't hurt, but it also isn't a real/proper mangling scheme. Just an g++ convention. It "demangles" to 'global constructors keyed to xxx'. According to the documentation the only prefix you should check for is _Z: http://mentorembedded.github.io/cxx-abi/abi.html#demangler If the user has a set of external names to demangle, they should check that the names are in fact mangled (that is, begin with "_Z") before passing them to __cxa_demangle.
