Creating 1000 instances

[Виталий Фадеев]

We have:
     class File
     {
         // WIN32_FIND_DATAW data;
     }

     void fastReadDir()
     {
         File[] files;

         // reserve space, allocating instances
         files = new File[]( 1000 );  // <--- trouble here ?

         // filling instances
         auto file = files.ptr;

         writeln( file.data );    // <--- or trouble here ?

         // ...
     }

Got:
     SegFault

Goal:
     Allocate memory for 1000 instances at once.

instances of the class File ?
