rootcint has never been able before version 2.24 to generate a correct
code for Streamer functions for classes containing pointers to basic
types. A warning message was always printed by rootcint.
The new version of rootcint can generate automatically correct code
if you tell what is the length of the array. The convention we have
adopted is to specify the length of the array in the comment field
of the data member declaration statement. In your case, do
Int_t n; //length of array
Int_t *array //[n]
The length of teh array is given in [n] where n must be a data member
declared in the header file before the definition of the array.
