1) win7 64
2) dmd 32
3) I don't catch explicitly. To ensure it isn't catch some way 
implicitly I just throw Exception without condition and it is thrown as 
expected
auto getObjectType() const {
         throw new Exception("Here the exception should be thrown!"); // 
works as expected
         KeyHeaderHelper value_header;
         value_header.ptr_ = cast(ubyte*) data_.ptr;
         return value_header.object_type; // if data isn't null it hangs 
up here
     }

moreover, when I provide data_ always have some length, the application 
starts hangin at return operator. I've met something like this behaviour 
(I mean silent hanging up) earlier working with std.concurrency, but I 
found some workaround. Now I dont know what to do.
