Follow-up Comment #4:

The only documentation I found for the MAT5 format is this:
https://www.mathworks.com/help/pdf_doc/matlab/matfile_format.pdf

I can't see that it specifically mentions how the context is stored with
function handles. So I guess our code is from reverse engineering. Is that
true?
If it is, it might be that we just didn't yet run across a file where this
wasn't a structure but it is empty.

I can't see how the change could break loading a file that previously loaded
successfully. And it allows loading the file from comment #0 successfully.

Since this fixes a bug, I pushed it to stable here:
https://hg.savannah.gnu.org/hgweb/octave/rev/6d37fa1a786e

Marking as ready for test.
