I use the ldc1.1-b5.
when I tach the Exception, in ldc, it not printf the stack info. 
in dmd ,it has.

import std.json;
import std.stdio;

string pjson(ref JSONValue js)
{
     return js["hhh"].str;
}

void main()
{
     JSONValue js;
     js["hh"] = 10;
     try{
         pjson(js);
     } catch(Exception e){
         writeln(e.toString());
     }
}

In ldc , only printf:
std.json.JSONException /build/src/ldc/runtime/phobos/std/json.d(442): Key not
found: hhh
----------------


In dmd , it printf:
std.json.JSONException std/json.d(442): Key not found: hhh
----------------
