Discussion:
register_callback allocates memory and so it can fail, but the case is unspecified. libc++ sets badbit, which is consistent with iword and pword. libstdc++ throws std::bad_alloc.
[2019-06-13; Billy comments]
Just as an additional data point: MSVC++ agrees with libstdc++ and also throws std::bad_alloc.
