Follow-up Comment #53, bug #58795 (project octave):

The types seem to match on the Debian buildbots (and also on my Ubuntu). But
they seem to be different on Fedora. E.g.:

There is still this note in the IDA manual (which isn't very enlightening to
me) [1]:
> A user program which uses sunindextype to handle indices will work with both
index storage types except for any calls to index storage-specific external

And jwe observed the following:
> The sundials wrappers for BLAS functions use sunindextype, so it appears
that it should match the size used by BLAS.
> See the file sundials-5.3.0/include/sundials/sundials_lapack.h, for
> Since it is used in the prototypes for calling BLAS/Lapack functions inside
sundials, then it seems we are forced to make it match the size of the type
used for BLAS integers (octave_f77_int_type).

So is this a packaging issue in Fedora? (Probably not very likely.)
Or an error in Sunlinsol?
Or is there more to it?
