Follow-up Comment #1, bug #58795 (project octave):

Somehow savannah does not display all the message.

Details:

MXE Octave (hg id a65cacd05892) was configured to cross-compile Windows 32bit
executables with:

./configure --with-pkg-dir=../mxe-octave-pkg --with-ccache
--enable-octave=default --enable-binary-packages --enable-qt5
--enable-devel-tools --disable-windows-64 --disable-64
--disable-fortran-int64
--disable-system-opengl
-vebatim-

On Windows 10 2004 64bit (and according to bug #58790 also on Windows 7), the
tests for ode15i and ode15s fail with the following errors:

>> test ode15i

[IDA ERROR]  IDASolve
  At t = 0, the linear solver setup failed unrecoverably.

***** testif HAVE_SUNDIALS_SUNLINSOL_KLU
 opt = odeset ("Jacobian", @jacfunsparse, "AbsTol", 1e-7, "RelTol", 1e-7);
 [t, y] = ode15i (@rob, [0, 100], [1; 0; 0], [-1e-4; 1e-4; 0], opt);
 assert ([t(end), y(end,:)], fref, 1e-3);
!!!!! test failed
IDASolve failed
>> test ode15s

[IDA ERROR]  IDASolve
  At t = 0, the linear solver setup failed unrecoverably.

***** testif HAVE_SUNDIALS_SUNLINSOL_KLU
 opt = odeset ("MStateDependence", "none",
               "Mass", sparse ([1, 0, 0; 0, 1, 0; 0, 0, 0]),
               "Jacobian", @jacfunsparse);
 [t, y] = ode15s (@rob, [0, 100], [1; 0; 0], opt);
 assert ([t(end), y(end,:)], frefrob, 1e-3);
!!!!! test failed
IDASolve failed


This might be a problem with SUNDIALS IDA 32bit itself or with how we are
using it.

In case this should matter, MXE Octave bundles SUNDIALS IDA version 5.3.0 and
SuiteSparse version 5.7.2.
