--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to tmmikolajczyk from comment #0) > The compilation passes (on gcc and clang). It's quite weird that the > virtualism of the "X::bar" method has such an impact. But that doesn't make it a bug. > Please also consider the following sligthly modified "X::bar" method: > > virtual void bar(const T& inst) const > > Gcc silently accepts such code. but clang rejects it: That is probably just because GCC has some bugs regarding access checking in function templates, see PR 59002
