I didn't understand where the difference is. Can you send me the full 
output files or the example that created it?

about the array. By default index1_data is preallocated to the maximal 
size (=n+1) because this size is known a priori. It is not initialized 
to zero. Thus only the first 'filled1' number of elements is useful. If 
you need a fully populated index1_data array you have to call 
complete_index1_data() first.
The array index2_data should have nnz() elements similar to value_data.

btw. how do you copy the data? operator = () and the copy constructor 
simply copy all internal values and arrays - thus the garbage is copied too.
