https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80251 --- Comment #2 from Jonathan Wakely --- It's only existed for less than a month,. and it requires a new intrinsic from the compiler which doesn't exist yet.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80251 --- Comment #1 from gcc-bugs at marehr dot dialup.fu-berlin.de --- I'm sorry for the inconvenience! I didn't see that is_aggregate was just a recent addition to the standard [1]. I just wanted to see if I can check at compile time if my data structure is an aggregate type, like I can do with is_pod. And I just happened to find such a function on cppreference, but I didn't realize that this was added quite recently. [1] http://open-std.org/JTC1/SC22/WG21/docs/papers/2017/p0625r0.html#2911
