--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed, 4.9.x rejects the code:
pr80805.cpp: In instantiation of ‘g()::<lambda()> [with D = int; X = <type
error>]’:
pr80805.cpp:12:6: required from ‘struct g() [with D = int]::<lambda()>’
pr80805.cpp:16:7: required from ‘void g() [with D = int]’
pr80805.cpp:18:21: required from here
pr80805.cpp:15:18: error: the value of ‘H’ is not usable in a constant
expression
return X{};
^
pr80805.cpp:10:27: note: ‘H’ used in its own initializer
constexpr static bool H = P<D>::value;
^
pr80805.cpp:15:18: note: in template argument for type ‘bool’
return X{};
