[Octave-bug-tracker] [bug #60620] [octave forge] (optim) 'expfit' function from optim-1.6.1 package terminates with segmentation fault

[anonymous]

Follow-up Comment #2, bug #60620 (project octave):

[comment #1 comment #1:]
> Can you show or upload the contents of 4th input arg y?

The contents are given by the following line in the original screen session:

"
octave:2> y = rand(1, 1024);
".

Or here is a one-liner:

"
octave:36> expfit(512, 0, 1, rand(1, 1024))
Segmentation fault (core dumped)
".

And another one-liner - much smaller dataset:

"
octave:5> expfit(16, 0, 1, rand(1, 32))
Segmentation fault (core dumped)
"

> I tried with dev Octave (7.0.0) but that just complained about "error: 'y'
undefined ..."

Please see the above.

> BTW Octave-4.2.2 is old and unsupported, could you upgrade to v. 6.2.0 and
try again?

This would mean a lot of hassle for me, and I suspect the problem is within
the package which was built using the '-forge' option, so it's probably the
newest or the problem is within a linear algebra library.
