//---'new' - parameter passed as reference, variable expected
   C201022_090654 c_2(new C201022_090641(1)); //not works

So pass a variable

   C201022_090641 *p=new C201022_090641(1);
   C201022_090654 c_2(p);
   // p lost here memory leak.

William Roeder:

So pass a variable

you're so smart, and adaptive, and observant.

why don't you make something useful offline?

If you want to point out a compiler bug, there's a thread in the Russian forum. I think the devs don't read here.
