            Bug ID: 15445
           Summary: istream fails to parse long numeric string correctly
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: release blocker
          Priority: P

The following code fails as reading stops on the '+' character (but that's not
the bug, removing the '+' from the string still causes it to fail).

#include <sstream>
#include <cassert>

int main(int argc, char** argv)
   std::stringstream ss;
   ss <<
   long double d;
   ss >> d;
   //char c = ss.get();
   assert(ss.rdbuf()->in_avail() == 0);
   return 0;

The rational for wanting to do this, is that we have both numeric constants and
test data expressed as a string - sometimes this is read into a multiprecision
type, and sometimes into a native type.

The failure is with SVN Trunk BTW.
