[Octave-bug-tracker] [bug #56232] Octave crash when inverting an empty sparse matrix.

[Rik]

Follow-up Comment #46, bug #56232 (project octave):

Remaining things to review

1) Use of &dummy in dSparse.cc, CSparse.cc, sparse-chol.cc

I think these were put in when the data pointer for a sparse matrix could be
NULL.  This can't happen anymore and so can probably be removed.

2) Use of nzmax in mex.cc

I didn't look at this, but I think mxSetNzmax (or somewhere in the chain)
needs to be modified so that it can't set a value of 0.  Also, the
constructors for class mxArray_sparse probably need to be modified like the
Octave ones in Sparse.h so that they always create valid pointers.
