The line numbers don't seem to match what I see in _spatial_.cc at revision faa0a913015f. Regardless, the problem seems to be with the following function:

A first weirdness is that it's templating the return value ET_OUT, yet it's always returning a double. I think the template argument ET_OUT is probably unnecessary, or else entropy should be changed to type ET_OUT so that it can use both float and double types.

As to the actual bug, I assume the problem is that `vals (i) + add` is returning octave_int8 values, but those can't be used for indexing. I don't even know why this used to work. I can't see what conversion path was used when octave_idx_type was int.

I think a simple fix might be to change those lines to

Mike: That is what I thought. Just checking for the record.

Packages can be built and installed for both, but no a package built for 32-bit-indexed Octave won't work with 64-bit-indexed Octave, and vice versa.

Right, but can a package built with 64-bit indexing run
with 32-bit indexing Octave in any case?

No, this is not a release blocker. This relates to the image package anyway, not to any failure within Octave.

Mike: Just a clarification: is 64-bit integer build
supported for the 4.0 release? I thought that it is

So if 64-bit is not not supported, this needs fixing,
but not before 4.0 release.

Confirmed, still fails to install using the current development branches of Octave (built with 64-bit index type) and the image package. At a glance the error messages look the same.

The following bug was reported on the mailing list by Fredrik Lingvall <fredrik.lingvall@gmail.com>. Original can be seen on nabble.

I have Octave configured with --enable-64 and I can't get the image package to build with this setup:
