--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Confirmed:

struct A { };

namespace {

  void thisThrows() {
    throw A();
  }

  struct SomeRandomType {};
}

int main() {
  try {
    thisThrows();
  }
  catch(SomeRandomType) {
    throw;
  }
  catch(A) {
  }
}

$ g++ throws.cc && ./a.out
$ g++ throws.cc -fPIC && ./a.out
$ g++ throws.cc -fsanitize=address && ./a.out
$ g++ throws.cc -fsanitize=address -fPIC && ./a.out
terminate called after throwing an instance of 'A'
