[Octave-bug-tracker] [bug #56037] qp exits with an indexing error for a specific input with OpenBLAS

[Mike Miller]

Update of bug #56037 (project octave):

                  Status:               Need Info => Confirmed              
                 Summary: Qp function crashes for a specific input => qp exits
with an indexing error for a specific input with OpenBLAS

Follow-up Comment #3:

I can confirm the error reported here with both Octave 4.4 and 5 using
OpenBLAS


p = 2 * [-1; ones(7,1)] * [-1, ones(1,7)];
q = zeros (8,1);
lb = zeros (1,8);
ub = ones (1,8);
a = ones (1,8);
b = 1;
[x, info, obj, lambda] = qp ([], p, q, a, b, lb, ub)


error: index (_,4): but object has size 3x3
error: called from
    qp at line 413 column 29:


If I use BLAS instead, I get a solution, but a different result than the one
shown by Dmitri in comment #2.
