--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r210017.  Before that it has been rejected:
pr77522.C: In function ‘void f(T)’:
pr77522.C:3:18: error: cannot capture ‘f’ by reference
   auto g = [&a = f] () {};
                  ^
pr77522.C: In instantiation of ‘struct f(T) [with T = int]::<lambda>’:
pr77522.C:3:25:   required from ‘void f(T) [with T = int]’
pr77522.C:8:7:   required from here
pr77522.C:3:18: error: unable to deduce ‘auto’ from ‘f’
pr77522.C:3:18: error: using invalid field ‘f(T)::<lambda()>::a’
