#9255: Serialization of negative long value to stringstream throws exception.

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  serialization
  Version:  Boost 1.54.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------------
 I am using the boost 1.54 serialization with the binary archive to
 serialize some basic data. This works great across several platforms in
 all cases except one. When I try to serialize a negative long value an
 exception is raised on OS X 10.7.5 building with clang 425.0.28.

 For example, the following example works fine on Windows 8 (visual studio
 2012) and Ubuntu (gcc) but fails on OS X (clang).

 {{{
 #include <sstream>

 #include <boost/archive/binary_iarchive.hpp>
 #include <boost/archive/binary_oarchive.hpp>


 int main(int argc, char * argv[])
 {

     long original = -1; // A non-negative value works fine
     long value = 0;

     // Serialize
     std::ostringstream oss;
     boost::archive::binary_oarchive out(oss);

     out << original;

     // Deserialize
     std::istringstream iss(oss.str());
     boost::archive::binary_iarchive in(iss);

     in >> value;    // exception raised here on OS X if original is a long
 < 0

     return 0;
 }
 }}}

 I can get the above to work by doing any of the following:
 - Changing to from binary archives to text archives
 - Using a type other than long (e.g, signed int is fine)
 - Assigning a positive value to original (but keeping type a long)
 - Using file streams instead of string streams
