[Bug libstdc++/30561] New: istream::operator>>(int&) broken

[sebor at roguewave dot com]

Here's a test case for the problem I point out in c++std-lib-17897. It shows
that operator>>(int&) behaves differently (and, I claim, incorrectly) from
operator>>(long&) or any other extractor except the one for short (which is
affected for the same reason).

$ cat t.cpp && g++ t.cpp -static && ./a.out
#include <cassert>
#include <locale>
#include <sstream>

struct NumPunct: std::numpunct<char>
{
    std::string do_grouping () const { return "\3"; }
    char do_thousands_sep () const { return ';'; }
};

template <class T>
T extract (const char *s)
{
    std::istringstream strm (s);
    strm.imbue (std::locale (strm.getloc (), new NumPunct));

    T x = T ();
    strm >> x;
    assert ((strm.failbit | strm.eofbit) == strm.rdstate ());
    return x;
}

int main ()
{
    assert (123L == extract<long>("1;2;3"));
    assert (123  == extract<int>("1;2;3"));
}

Assertion failed: 123 == extract<int>("1;2;3"), file t.cpp, line 26
Abort (core dumped)

The resolution of the DR is implemented in mainline.
