Andrei,
Your program seems to crash while doing memory allocation in the
TTree::AutoSave function.
In your example, you create a file with a virtual size of 16 GBytes compressed
to about 1 GByte. You are creating a huge number of baskets (362526).
It would greatly help if instead of basket sizes of 32K, you had 512K.
Could you send me the output of gObjectTable->Print() just before it crashes.
Could you also watch teh memory used by teh system if you can monitor it
on your machine ?
