           Summary: money_get does not get "$.00"
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org

I'm having a problem on gcc-3.2.3 and gcc-3.3 getting the money_get facet to
parse "$.00".  It is happy with things like "$.01" though.  (I haven't been able
to test it with anything more recent because I'm getting errors every time I try
to compile something from cvs.)

The problem is reproduced in the following code.  After compiling, I run it as

    LANG=en_US.UTF8 ./main

The output I get is

    amount = 5
    amount = 4
    amount = 3
    amount = 2
    amount = 1
    amount = <error>

The "<error>" corresponds to "$.00".

===================

#include <locale>
#include <string>
#include <sstream>
#include <iostream>

using namespace std;

namespace {

    void doit(const string& amount)
    {
        // Use a non-trivial locale by setting LANG=en_US.UTF8 (for
        // example).
        istringstream istrm(amount);
        istrm.imbue(locale(""));

        // Retrieve the money_get facet.
        const money_get<char>& mgf =
            use_facet< money_get <char> >(istrm.getloc());

        // Use the facet to extract the amount from istrm.
        string extracted_amount;
        ios_base::iostate err = ios_base::iostate(0);
        mgf.get(istrm, 0, false, istrm, err, extracted_amount);

        // Check for errors.
        if( err & ios_base::failbit ) {
            extracted_amount = "<error>";
        }

        // What did we get?
        cout << "amount = " << extracted_amount << endl;
    }

}

int main(int argc, char* argv[])
{
    int rv = 0;
    doit("$.05");
    doit("$.04");
    doit("$.03");
    doit("$.02");
    doit("$.01");
    doit("$.00");
    return rv;
}
