[Octave-bug-tracker] [bug #46449] Address-sanitizer triggered in scripts/sparse/ichol.m

[Robert Jenssen]

Follow-up Comment #9, bug #46449 (project octave):

Some anecdotal evidence in response to JWE's comment about OpenGL:

1. I find that when using the stock Fedora 23 build of octave-4.0.0 I get
different numerical output from the same script run repeatedly. When I use an
octave that I have built without native graphics I don't see this. (Where my
octave uses the numerical libraries supplied by the Fedora 23 installation).

2. I have been trying to track down a similar problem with the SeDuMi_1_3
solver running under an octave built without native graphics. I think that
maybe, possibly, I have solved this one by using address-sanitizer to find an
error in which an array of doubles was read one location beyond the end (in
cholonBlk()).
