--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Bug 89370 would really help simplify this diagnostic.
The last three lines would be:
.../src/NCPkgFilterPattern.cc:343:28: required from here
/usr/include/c++/11/bits/stl_tree.h:770:8: error: static assertion failed:
comparison object must be invocable as const
770 |
| ^
/usr/include/c++/11/bits/stl_tree.h:770:8: note: ‘std::is_invocable_v<const
paircmp&, const std::pair<std::string, std::string&, const
std::pair<std::string, std::string&>’ evaluates to false
Which is pretty clear, I think.
