today when testing D i found out, that i can't compare a reference with 0, i always get a segmentation fault. Please look at this code:

Code:

import std.stdio;

class Test2
{
   int a, b;
}

class Test
{
   Test2 test = null;

   void foo( )
   {
      if( test == null ) writefln( "adfsfd" );
   }
}

void main( char[][] args )
{
        Test test = new Test();
        test.foo();
}
