Hi Rene,

I have some more information on my problem.

As I explained, I put a gObjectTable->Print() inside the loop in which the 
operator ``new'' is called:

>-------------------------------------------------<

>   for (h=0; h<fNFrag; h++)
>     {
>       cout<<"h = "<<h<<endl;
>       fTCDrawer = new (Drawer[h]) TC_Drawer();
>       printf("Pointer Drawer = %x\n", Drawer[h]);
>       printf("Pointer fTCDrawer = %x\n", fTCDrawer);
>       fTCDrawer = (TC_Drawer*)Drawer[h];
>       printf("Pointer fTCDrawer = %x\n", fTCDrawer);
>       Fill_Drawer (Fragment[h], fTCDrawer);
>       if (h == 5) gObjectTable->Print();
>     }

The news is that I check more accurately the root answer.
If the program works correctly I can one TC_Drawer istance,
but I gain the following error messages

Error in <TObjectTable::UpdateInstCount>: oops 0x088681e8

Error in <TObjectTable::UpdateInstCount>: oops 0x08868be8

Error in <TObjectTable::UpdateInstCount>: oops 0x0886a6d0

Error in <TObjectTable::UpdateInstCount>: oops 0x0886c510

Error in <TObjectTable::UpdateInstCount>: oops 0x0886e1f8

These are exactly exadecimal value of pointers printed in loop.
And they are five, as more as the missing istances.

If the program crashes the error messages are six, as expected after the 
previous behaviour:

Error in <TObjectTable::UpdateInstCount>: oops 0x0887ff48

Error in <TObjectTable::UpdateInstCount>: oops 0x0886bbe0

Error in <TObjectTable::UpdateInstCount>: oops 0x0886b028

Error in <TObjectTable::UpdateInstCount>: oops 0x08875f80

Error in <TObjectTable::UpdateInstCount>: oops 0x08867e58

Error in <TObjectTable::UpdateInstCount>: oops 0x08869818

Something is going bad with memory, but what?

What's more, in the first case TTree seems to be correctly build up and 
filled. But now it's better if I try to check it.

Cheers,
