[Stlport-devel] Monetary do_get() problems

[Kees de B. <kee...@al...>]

Hi,

With the following test program I get the "Unexpected result" message:

#include <locale>
#include <iterator>
#include <sstream>
#include <string>

#include <cstdio>

#define IOS_BASE std::ios_base
#define MONEY_GET std::money_get<char>
#define ITERATOR std::istreambuf_iterator<char>

struct D : public MONEY_GET {
         D() : MONEY_GET() {}
	iter_type do_get(iter_type s, iter_type end, bool intl,
		     IOS_BASE& str, IOS_BASE::iostate& err,
		     long double& units) const {
             return MONEY_GET::do_get(s, end, intl, str, err, units);
	}
	iter_type do_get(iter_type s, iter_type end, bool intl,
		     IOS_BASE& str, IOS_BASE::iostate& err,
		     string_type& digits) const {
             return MONEY_GET::do_get(s, end, intl, str, err, digits);
	}
} d;

int main(void)
{
         std::istringstream in00("1 ");
         in00.imbue(std::locale::classic());
         in00.exceptions(IOS_BASE::goodbit);

         long double val00;
         ITERATOR end00;
         ITERATOR beg00(in00);
         IOS_BASE::iostate prior_err00 = in00.rdstate();
         IOS_BASE::iostate err00 = in00.rdstate();
         d.do_get(beg00, end00, true, in00, err00, val00);
         if (err00 != prior_err00)
                 std::printf("Unexpected result.\n");

	return 0;
}

Using latest GIT repository I have traced this back to the function 
__get_monetary_value(), line 106. The "++__first;" statement will advance 
an additional character after the actual characters of the monetary value 
(in the example the trailing space) and this causes the eofbit flag to be set.
