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

Follow-up Comment #10, bug #31479 (project octave):

Right, I forgot about the advantages of Open Source; it hadn't occurred to me
to just grab the code and fix it.  From a process perspective, I think this is
the best option as I see little hope of getting the original developers to
update their code.  The license for ARPACK is at
http://www.caam.rice.edu/software/ARPACK/.  Does the top, BSD Software
License, incorporate terms by reference other than the one's listed on this
page?  If not, the license isn't onerous and it should go in before the 3.4
release.  

After it goes in, we might want to take a look at a few of the
distro-provided ARPACK packages to see if the package maintainers are throwing
in any special flags for the compilation.  It might also be worth benchmarking
the current situation.  It would be a shame to introduce an Octave-compiled
version of the library which results in lower performance than a distribution
installed version.
