[Octave-bug-tracker] [bug #36656] deleting rows from sparse matrices leads to failed assertion sometimes

[David Bateman]

Follow-up Comment #4, bug #36656 (project octave):

Given the assertion that is failing this is the same issues as for the bug
#36104. With the same fix

http://hg.savannah.gnu.org/hgweb/octave/rev/8d2ce821e38a

That is somewhere the constructor

rep = new SparseRep (nr, nc);

and it needs to be replaced with 

rep = new SparseRep (nr, nc, 0);

to ensure that the values in ridx are valid. In fact given this issue the
constructor SparseRep(nr,nc) probably shouldn't be used. So the easiest fix
would be just to rewrite this to use SparseRep(nr,nv, 0) instead.
