[pkg-boost-devel] Bug#584325: libboost1.42-dev: Interval library returns nan instead of the correct interval

[Christophe Troestler]

Package: libboost1.42-dev
Version: 1.42.0-3
Severity: important

The program below, compiled with no optimizations, returns [nan, nan]
instead of the correct answer on my 64 bit machines.  On 32 bits, it
works fine.

----------------------------------------------------------------------
#include <boost/numeric/interval.hpp>
#include <fstream>
#include <iostream>

using namespace boost;
using namespace numeric;
using namespace interval_lib;

typedef interval<double,
                 policies<save_state<rounded_transc_opp<double> >,
                          checking_base<double> > > I;

template<class T, class Policies>
std::ostream &operator<<(std::ostream &os,
                         const boost::numeric::interval<T, Policies> &x) {
  os << "[" << x.lower() << ", " << x.upper() << "]";
  return os;
}

int main()
{
  std::cout << cos(I(-1, -0.6)) << "\n";
}
