I just ran into this today. The referenced "dup" seems to have been resolved
last June, but this is still failing. Also probably the same as
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99495.
Is there any chance someone could take a fresh look at this?

The problem is the default Destructor in the Derived for the other examples.
So this can be reduced to just:
struct Base
{
constexpr virtual ~Base() = default;
};
constexpr Base b;

c++: constexpr error with defaulted virtual dtor [PR93413]
We're rejecting the below testcase with
error: 'virtual constexpr Base::~Base()' used before its definition
error: 'virtual constexpr Derived::~Derived()' used before its definition
due to special handling in mark_used added by r181272 to defer synthesis
of virtual destructors until EOF (where we can set their linkage), which
in turn makes them effectively unusable during constexpr evaluation.
Fortunately it seems this special handling is unnecessary ever since
r208030 enabled us to tentatively set linkage of all defaulted virtual
destructors, including templated ones. So this patch gets rid of this
special handling.
PR c++/93413
gcc/cp/ChangeLog:
* decl2.cc (mark_used): Don't defer synthesis of virtual
functions.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/constexpr-virtual21.C: New test.

--- Comment #11 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Fixed for GCC 13. The fix is probably unsuitable for backporting, and there
are workarounds anyway -- one workaround is to turn the problematic class into
a class template with an explicitly defaulted dtor, e.g. for the original
testcase do:
struct Base {
constexpr virtual ~Base(){}
};
template<class=void>
struct Derived: Base {
~Derived() = default;
};
constexpr Derived<> d;
