--- Comment #11 from Martin Liška <marxin at gcc dot gnu.org> ---
There's a self-container test-case:
$ cat resolver.ii
class Resolver {
int GetCMIName();
virtual char GetCMISuffix() { return 'c'; }
};
int Resolver::GetCMIName() { GetCMISuffix(); return 0; }
int main() {}
$ -static-libstdc++ -static-libgcc -fsanitize=undefined -static-libubsan
[fine]
$ g++ -fsanitize=undefined resolver.ii -static-libstdc++ -static-libubsan
