Hi rooters,
i'm experiencing a segmentation violation error when reading a big
ASCII (1GB) file.
It starts correctly the analysis but at a certain point it gives me
the following error and exits out from the routine.
- Break *** segmentation violation

Do you think it is a problem of the size of the file? If this could be
the case i can create a TTree file and work there, but i would like to
be sure that the size CAN be a cause of segmentation violation before
changing all the routine to read from a TTree.....
Please note that i' using ROOT version 5.13/03
Thanks in advance,
Marco Calviani
