--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
Reduced test-case:

$ cat semantic.C
#pragma GCC optimize 0
template <typename T> void foo(T);
struct B {
  ~B() {}
};
struct C {
  B f;
};
template <typename> struct E {
  void bar() { foo(g); }
  C g;
};
template class E<char>;

$ g++ semantic.C  -c -Ofast
semantic.C:13:23: error: semantic interposition mismatch
   13 | template class E<char>;
