This pattern happens more often in pb_ds.
If I replace the casts by static_cast<>s and const_cast<>s the problem
persists though. I do not see that the frontend produces a FIELD_DECL
for the Eq_Fn base of hash_eq_fn (nor a field for hash_eq_fn base of
gp_ht_map_data_). Thus the static_cast fails to do the proper pointer
adjustment to a padding field (but stays pointing to the vtable pointer).
Obviously hash_eq_fn and Eq_Fn as they are empty classes end up in
tail-padding somewhere.
Let's get some C++ folks in here.
