unfortunately, situation been not that simple == seems there is 
problem to initialize class GmpInt properly: i made two funcs to 
create class..
[zz.mk](https://github.com/SarK0Y/DLang/blob/556fefa36e51b46a80de3717d8c495842c36224f/source/class_gmp_z.d#L141)

```D
  static zz* mk () {
         auto __zz = new zz(0);
         auto size_zz = __traits (classInstanceSize, GmpInt);
         auto alloc_zz = cast (zz) malloc (size_zz);
         alloc_zz = __zz.dup;
         alloc_zz.name = "alloc_zz";
         alloc_zz.prnt;
         zz* ret = &alloc_zz;
         ret.prnt;
         return ret;
     }
```
[zz._mk](https://github.com/SarK0Y/DLang/blob/556fefa36e51b46a80de3717d8c495842c36224f/source/class_gmp_z.d#L152)

```D
     static zz* _mk()
     {
         auto __zz = new zz(0);
         zz* ret = &__zz;
         return ret;
     }
```
in short, not sufficient allocation is very culprit here..

PS. variant w/ malloc runs more stable :)
