Benjamin Bannier commented on MESOS-4045:
-----------------------------------------

With a test program
{code}
#include <iostream>
#include <sstream>

int main() {
  std::stringstream ss;
  ss << std::hex;
  ss << "0x10.0";
  double d = -1;
  ss >> d;
  std::boolalpha(std::cerr);
  std::cerr << ss.fail() << " " << ss.eof() << "\n";
  std::cerr << d << "\n";
}
{code}

under OS X for for clang-3.8.0 I get
{code}
false true
16
{code}
while for gcc-5.2.0 there
{code}
false false
0
{code}

> NumifyTest.HexNumberTest fails
