[Octave-bug-tracker] [bug #31479] Crash & bugs in eigs

[David Bateman]

Follow-up Comment #5, bug #31479 (project octave):

I hope you read my mails

http://octave.1599824.n4.nabble.com/eigs-crash-on-a-particular-spare-matrix-td1673964.html#a1673970

and numerous others about this problem which has dated back to 2006? Making
the change in ARPACK seems impossible (though maybe in PARPACK it might be
possible). Getting a distribution to patch ARPACK themselves seems to best
route to me, and for this we need a self-contained ARPACK example
demonstrating the problem something I tried to do a few times, but never got
around to finalizing. I'd prefer this solution to patching Octave to
workaround a bug in ARPACK
