THnSparse projection

Hi,

i want to project a 5 dimensions THnSparse into a 3 dimensions THnSparse: The code i used is:

 THnSparseD *h_obs;
 THnSparseD *h_obs_proj;

  int ndim =3;
  int dim[3]; // i select the three axis i want to project

  dim[0]=0;
  dim[1]=1;
  dim[2]=4;

  h_obs_proj = (THnSparseD*) h_obs -> Projection(ndim, dim,"E");  

where h_obs is the 5D THnSparseD.

This code does segmentation fault but i don't know why.

Thanks,
