Description

The following program fails on assert.

#include <cassert>
#include <sstream>
#include <string>

int main ()
{
    typedef std::num_get<char> NumGet;
    typedef std::istreambuf_iterator<char> Iter;

    std::locale loc;

    for (unsigned i = 0; i < 10000; ++i) {
        std::string s (i, '0');
        s.push_back ('1');

        std::istringstream is (s);

        std::ios::iostate state = std::ios::goodbit;
        long val = 0;

        std::use_facet<NumGet> (loc).get (Iter (is), Iter (), is, state, val);
        assert (1 == val && std::ios::eofbit == state);
    }

    return 0;
}
