Follow-up Comment #30, bug #58795 (project octave):
On my Debian system, I see
typedef int32_t sunindextype;
in the file /usr/include/sundials/sundials_types.h.
I assume this is needed to match the use of 32-bit integers for indexing and
integer work arrays in the system BLAS library.
In Octave on 64-bit systems using the default int64_t for 64-bit indexing, we
can still use 32-bit BLAS (and other) libraries if we are careful to avoid
calling those library functions when the array sizes are too large. I don't
know whether we are already doing it, but we may need to do the same for
Sundials.
On 32-bit systems, I don't expect it to be possible to use 64-bit indexing, so
all indexing and dimension variables should be limited to 32-bits.
If Sundials and/or some of the libraries it uses are configured by default to
use 64-bit indexing, then that's probably a mistake if they also need to call
32-bit BLAS functions.
If I remember correctly, SuiteSparse can be configured to use 64-bit indexing
and use a BLAS library that has 32-bit indexing because it is careful when
calling BLAS functions, same as Octave tries to do.
