Fixed on the development branch in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/085976d9ef08).  To access the fix you can build from Mercurial development sources or wait until the next major release of Octave.

If one has variable names longer than 31 characters they get truncated when using the default matlab binary save option (i.e., "save -mat-binary filename.mat "). I also tried "save -V6 filename.mat " (got the same result), and "save -V7 filename.mat *" (this retained long variable names, but it compresses the binary file, which takes a very long time when the Octave session holds on the order of GB of data).


FWIW, I originally posted a bug report about this ~6 years ago, and thought the problem had been fixed then. It seems like this might be a regression.
