+
+Essentially, the problem is that libstdc++'s std::unordered_map<T, U>
+implementation requires both T and U to be fully declared. I raised the
+problem in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92770, and GCC's
+position is that we are relying on undefined behavior according to the C++
+standard (https://eel.is/c++draft/requirements#res.on.functions-2.5).

-Subject: [PATCH] GCC: do not set noexcept on move assignment operator of ColorSet
-
-GCC build is broken because ColorSet default move assign operator is
-noexcept (because the color flat_map is not noexcept). It does not
-break clang because clang does not warn about this situation when
-building with -fno-exception.
-
-../../ui/color/color_set.cc:14:11: error: function ‘ui::ColorSet& ui::ColorSet::operator=(ui::ColorSet&&)’ defaulted on its redeclaration with an exception-specification that differs from the implicit exception-specification ‘’
- ColorSet& ColorSet::operator=(ColorSet&&) noexcept = default;
