3831,property_tree::read_json unable to handle large integers.,Michael Anderson <drmikeando@…>,Sebastian Redl,"Trying to read json that contains a value outside the range of an int into a property tree produces the following error
{{{

This is due to the use of a int_p parser in the spirit parsing code.
Applying the following patch
{{{

Seems to fix this.

The following example demonstrates the issue.
{{{
#include ""boost/property_tree/json_parser.hpp""
#include ""boost/property_tree/info_parser.hpp""

int main()
{
  boost::property_tree::ptree pt;
  std::string s(""{\""v1\"":124567890123,\""v2\"":+124567890123,\""v3\"":-124567890123}"");
  std::stringstream ss;
  ss<<s;
  boost::property_tree::read_json( ss, pt );
  boost::property_tree::write_json( std::cout, pt );
}
}}}
This outputs
{{{
{
    ""v1"": ""124567890123"",
    ""v2"": ""+124567890123"",
    ""v3"": ""-124567890123""
}
}}}
When the patch is applied.
