Comment 1 Vitaly 2022-01-17 08:46:59 UTC 
Changing the component to GCC, because the json upstream doesn't know how to fix this. Maybe it is just a simple GCC regression.
Comment 2 Jonathan Wakely 2022-01-17 09:59:04 UTC 
GCC now implements http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2020/p2166r1.html which requires this behaviour for C++23.

Even if we make the change only apply to C++23 and not earluier standards, the json library will need to be fixed eventually.
Comment 3 Vitaly 2022-01-27 10:08:01 UTC 
Fixed.
