This is wrong, you should use g++ to link as you need to link against libstdc++
which gcc does not do which is why you are not seeing it on gcc.godbolt.

stupid me - my cmake scripts uses g++, accidentally switched to gcc - thanks
so the -DTEST=2 is NOT a bug

Reduced testcase for the first issue (note it is a different error but the
problem is the same):
using Callback = void();
template <typename ValueType>
struct GetSetHelper
{
static void set( Callback callback_ = []() {} ){}
};
template <typename First>
void m()
{
GetSetHelper<First>::set();
}
template <typename... Types>
void n( )
{
( ( m<Types>( ) ), ... );
}
int main()
{
GetSetHelper<signed>::set();
n<signed, unsigned>( );
}

The ICE with reduced testcase:
<source>:21:1: error: Two symbols with same comdat_group are not linked by the
same_comdat_group list.
21 | }

But this is with checking turned on only.
Without checking we get an assembler failure:

Just lambdas as default is needed really, reduced testcase:
struct f
{
template<class T1>
f(const T1&){}
};
template<typename T> class A {
public:
void foo(A<T> a, const f& fn = [](){}) { }
void bar(A<T> a) { foo(a); }
};
int main() {
A<int> a;
a.foo(a);
a.bar(a);
return 0;
}

c++: lambda in template default argument [PR103186]
The problem with this testcase was that since my patch for PR97900 we
weren't preserving DECL_UID identity for parameters of instantiations of
templated functions, so using those parameters as the keys for the
defarg_inst map broke. I think this was always fragile given the
possibility of redeclarations, so instead of reverting that change let's
switch to keying off the function.
Memory use compiling stdc++.h is not noticeably different.
