--- Comment #4 from Markus Trippelsdorf <trippels at gcc dot gnu.org> --- Yeah, keeping the old behavior in the demangler would go against the raison d'etre of the ABI change. David's example _ZZ1gvEN1Y1fEZ1gvE1X_11C would then never demangle correctly. BTW there is another open ABI issue at: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70182#c9 Jason?
