It seems that this behavior related to Fiber class: 

import std.stdio;
import core.thread;

void foo()
{
   writeln("before");

   try
   {
     throw new Exception("Exception");
   }
   catch (Throwable ex)
   {
     writeln(ex.msg);
   }

   writeln("after");
}

void main()
{
   Fiber fiber = new Fiber(&foo);
   fiber.call();
}

There is an open ticket for DMD:

I also often get crashes on my Win8 system, but I didn't manage to take
the time to reduce this to a minimal test case. It doesn't fail for the
simple ones above.
