    Not a bug: see (or Stroustrup, p. 557). In a
    nutshell, reverse_iterator is implemented in terms of a
    plain iterator (called 'current' in the standard) which
    points one position forward. Therefore, in your testcase, upon erase(90), jt 'current' iterator (which points to 90)
    is invalidated.
