I can't reproduce this with current trunk, I just get these errors:

tst.cc: In instantiation of ‘Foo::test():: [with auto:1 =
int]’:
tst.cc:6:35:   required by substitution of ‘template
Foo::test()::::operator decltype
(((Foo::test()::)0u).operator()(arg)) (*)(auto:1)() const [with
auto:1 = int]’
tst.cc:10:17:   required from here
tst.cc:8:29: error: cannot call member function ‘void Foo::X() [with
 = int]’ without object
 X();
 ^~

tst.cc: In instantiation of ‘Foo::test():: [with auto:2 =
int]’:
tst.cc:12:35:   required by substitution of ‘template
Foo::test()::::operator decltype
(((Foo::test()::)0u).operator()(arg)) (*)(auto:2)() const [with
auto:2 = int]’
tst.cc:15:17:   required from here
tst.cc:13:29: error: cannot call member function ‘void Foo::X() [with
 = int]’ without object
 X();
 ^~

Can anyone else, or should we close it?

Agreed, the ICE seems to be fixed on trunk. However, the error you're getting
is still a bug, right? The code compiles if I use `this->X()`,
but not `X()` alone.

Yes, it seems like a dup. However, it would still be nice to know when this bug
was fixed, because it seems unlikely to have been fixed by chance... It could
be that something's still wrong, but the compiler simply doesn't ICE anymore.

At any rate, this can be closed as a duplicate of PR61636.

Not sure, you'd have to ask the C++ folks. You mentioned PR61636 though, and
that looks similar - is this one a dup?

With -std=c++1y an ICE started with r200948.

(But it's a different ICE than the one in the Description.)
