--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
IIRC the problem is that std::optional's copy ctor is defaulted, and in such
cases GCC doesn't show where a defaulted ctor is first needed. It just shows
the location as the location of the class itself. There might already be a bug
report about this.
