Follow-up Comment #1, bug #43383 (project octave):
I think you are using memset incorrectly here. The last argument is the
number of bytes, so I think you should be multiplying by sizeof. But since
this is C++ code, maybe it would be better to use std::fill?
But in any case, I think the static analysis is showing a false positive here
because len is equal to the number of non-zero elements in the data vector, so
the loop should set all elements of idata.
