Synopsis: basic_istringstream<unsigned xxx> causes segfault

State-Changed-Why:
    Reproduced with 3.1 20020310 and 3.2 20020310 (both
    segfaults before any output).  I don't think this has ever
    worked before, so it's technically not a regression.  A
    similar problem is under discussion on the libstdc++ list.
