Started with r202605.  Before:
/opt/notnfs/polacek/x.ii: In lambda function:
/opt/notnfs/polacek/x.ii:37:30: error: ‘const’ qualifiers cannot be applied to
‘const gen::CMembers’
   [=] { [] { auto dummy = {(bs, 0)...}; }; };
  ^
/opt/notnfs/polacek/x.ii:37:36: error: expansion pattern ‘(bs, 0)’ contains no
argument packs
   [=] { [] { auto dummy = {(bs, 0)...}; }; };
^
/opt/notnfs/polacek/x.ii: In instantiation of ‘struct gen::build(GenT, const
gen::CMembers ...) [with T = Foobarint; Members = {void
(Foobarint::*)(), void (Foobarint::*)(), int Foobarint::*}]::lambda()’:
/opt/notnfs/polacek/x.ii:37:3:   required from ‘void gen::build(GenT, const
gen::CMembers ...) [with T = Foobarint; Members = {void
(Foobarint::*)(), void (Foobarint::*)(), int Foobarint::*}]’
/opt/notnfs/polacek/x.ii:48:37:   required from here
/opt/notnfs/polacek/x.ii:37:30: sorry, unimplemented: use of
‘type_pack_expansion’ in template
   [=] { [] { auto dummy = {(bs, 0)...}; }; };
  ^
/opt/notnfs/polacek/x.ii:37:30: error: using invalid field ‘gen::build(GenT,
