--- Comment #4 from Andreas Fertig <src at andyf dot de> ---
Thanks for looking into the issue!

While CWG 2585 tweaks the wording, my reading is that the code should be va=
lid
even with C++20.

Regardless of that, without the lambda, the code compiles and uses a custom
allocator.=20

After playing with the test case, I could reduce it to having only a
coroutine-lambda with a promise_type that has a custom operator new:

Sorry for not having that done initially!

I suspect this case wasn't implemented (because it isn't obvious?).=
