[Octave-bug-tracker] [bug #58795] ode15i and ode15s fail if sunindextype and octave_idx_type are incompatible

[Hg200]

Follow-up Comment #22, bug #58795 (project octave):

Follow-up

1.)
The bug appears consistent with the occurrence of sparse matrix
representation. Attached is a minimum working example. With and without sparse
- keyword. If

++
sparse()
--

is removed, the example runs successful as w32 target. 

2.)
The test with mxe-octave on win64 target (on Windows 7), with int32_t
octave_idx_type and int64_t sunindextype

++
./configure --with-pkg-dir=../pkg_mxe_64/ --with-ccache
--enable-octave=default --enable-binary-packages --enable-qt5
--enable-devel-tools --enable-windows-64 --disable-64 --disable-fortran-int64
--disable-system-opengl
--

did *not* force the bug. Maybe it's an inconsistency between suitesparse +
sundials-ida on a w32 target?

3.)
Off topic: I checked the fix on a MXE on Linux build. sundials log has a
warning:

-- Looking for KLU libraries... FAILED
WARNING: KLU LIBRARIES NOT Found.  Please check library path
/home/.../mxe-octave-64-linux/usr/lib

Maybe it is because libsundials_sunlinsolklu.* is not build for for Linux. I
would expect the preprocessor define "HAVE_SUNDIALS_SUNLINSOL_KLU" in
config.h. But config.h is removed after building default-octave, right?
