Bug - Try to use class object with no constructor = unhandled exception xc0000005

[Al W]

This was a pain to find. Definitely a new bug.

First, try this script as is. Then comment out: "Print(sad.Test())" ,and the exception disappears.

Note the class that has no constructor, but has an array doesn't cause an error. Just the ones without constructor or an array causes it...

class HasConstructor
{
   public:
   HasConstructor()
   {
   
   }
   int Test()
   {
      return(1);
   }
   
};

//this one causes exception when Test is called
class HasNoConstructor
{
   
   public:
   
   int testmember;

   int Test()
   {
      return(1);
   }
};


class HasArrayNoConstructor
{
   
   public:

   int testmember[];
   
   int Test()
   {
      return(1);
   }
};

//+------------------------------------------------------------------+
//| Script program start function                                    |

void OnStart()
  {
//---
   HasConstructor happy;
   HasArrayNoConstructor happy2;
   HasNoConstructor sad;
 
   Print(happy.Test());
   Print(happy2.Test());
   
   //comment this out and no more unhandled exception. 
   Print(sad.Test());
  }
