[Octave-bug-tracker] [bug #57435] Test suite crashes on Windows on sparse.tst

[Markus Mützel]

Update of bug #57435 (project octave):

                  Status:                    None => Patch Submitted

Follow-up Comment #22:

I cross-compiled with the attached patch (and SuiteSparse 4.5.6).
The test suite now completes without Octave closing unexpectedly.

Wrt Rik's comment #21: I believe this is what I did with the last 2 verbatim
blocks in comment #18. Before "clear functions", the pointers in the
SuiteSparse_config struct are valid and resolve to the functions as set in
amd.cc. After "clear functions", the pointers still have the same values. But
they point to invalid memory.

I'll try if I can get a newer version of SuiteSparse to cross-compile. But I
think that the problem is caused by Octave setting function pointers in the
global structure that can get out of scope.
The mlock is necessary. Or the functions shouldn't be (un-)loadable and moved
to Octave core like jwe suggested.
