--- Comment #2 from Marcus Hähnel <marcus.haehnel at kernkonzept dot com> ---
Another note: Having the return type of the wrap template not using decltype
(and hard-coding it to int) will make this work and not have an ICE.
So this seems to trigger when all of this is met:
* A template takes a function as value parameter with auto type
* Deduces the return type using decltype in the trailing return type
* The function that is wrapped has the format warning attribute
